How can I turn off Community Factbook Tags

That option is not currently available, although we have considered adding it at some point in the future.

Thanks. I would like to see this feature brought back.

what if I actually want to turn the feature on in all of my books, but I only want to see Faithlife's data? I'd actually love to have the Factbook tags on in all of my books and off in all of my Bibles until I want to see them. But I just want Faithlife data and not community data.

Exactly what I want. Faithlife tags have a higher level of credibility that community tags. I turn on community tags from time to time, but normally I want FL tags.

Is there any way for a user to create a private tag? 

There is not.

I thought the terminology Community Tags was more descriptive. User Tags sounds like my own personal tags.

Suggestions:

1. I would like the option to turn on/off separately my own tags from the tags of other users. 
2. I suggest for terminology: "Personal Tags" (for my own tags)
3. For the tags generated by other users, I would suggest "Popular Tags" to be consistent with "Popular Highlights". The older "Community Tags" terminology was quite clear.

I rarely disagree with you, Harry, but in this case I do. For Community Tags I would expect user invented tags resulting in the useless chaos of popular highlights or the less chaotic but still of very little use, the list of popular resource tags. These tags have always been limited to FL defined entities and extended the functions of Factbook entity searches - sometimes in Factbook itself, sometimes in user searches.

Perhaps I misunderstood what the user-created Factbook tags are. I had thought that they represented what librarians call a controlled vocabulary or authority list. This is how I believe Factbook worked in Logos 9. But in Logos 10 the Context menu command "Add Factbook Tag" makes it seem like the user can create their own tag. When the dialog pops up there is no pick list with a controlled vocabulary, until the user starts typing. So it appears as if the user can create their own random tags. This would indeed create a chaotic list of tags. In fact, it appears that is not the case. I don't think the user can actually create their own tag as it seemed to me at first. They must choose from existing tags that FL has created. This is as I believe it should be.

However, there is still much potential for chaos. I don't want the Factbook cluttered with random highlights that users create. Ideally, I would expect a curated selection of content from professionally edited secondary sources written by credible scholars. This is what Faithlife Study Bible provides and Factbook version 9 expanded on this type of material, but in topical format. I recognize that there is a certain degree of "serendipity" (as Bob used to call it), in that each user might have different entries in their Factbook, depending on what resources their have in their library. It appears that Factbook 9 added a manually curated main entry along with a certain number of machine-generated links to resources in the user's library along with some advertisements for additional resources in the Bookstore. I am fine with all of this.

What troubles me is that crowdsourced highlights seem to be added to the Factbook on the same level as the FL curated material. I would not be against this, if it is clearly identified as from the collective wisdom of many users of the software. But I believe there should be a way to turn these off when viewing the Factbook highlights in the resource and when viewing a Factbook article. They should also be distinguished in some way from the links built in to Factbook by Faithlife.

You are not part of this group, but there is a group of users who have consistently for years requested more ability of the users to enter tagging, labels, etc. that FL has not done. But when FL provides it, they neither put effort into making it work by adding quality tags nor use the work of others to convince FL that crowd sourcing can work.

I do think user-created tags and labels are a great idea, particularly if they are searchable and can be included in various reports. But I want to be able to distinguish my personal tags from the tags of other users, just as I want to distinguish my personal highlights and notes from those of others. Logos does this very well in notes and highlights and lets the user turn on or off these various types of notes and highlights in individual resources, depending on their needs and desires. I would love to have a similar capability in user-created Factbook tags. 

Conceptually I see 3 kinds of tags:

1. Built-in tags created by Faithlife that are part of various datasets that a user purchased.
2. Personal tags created by an individual user for their personal study.
3. Crowdsourced tags aggregated from many users. I suggested calling them "popular" tags, because I don't want to see every individual tag added each a single user. Rather I want the option to see tags that occur frequently enough that they reflect the collective wisdom of many users.
