I just found the Faithlife group Logos Syntax Searching which is a wonderful addition in support of syntax searches. The other document that we have had great contributions in is the Sentence diagram. I was tempted to create a group and add everything I've collected over the years (other people's work) into it. But somehow it seems more appropriate for the group to have a Logos name on it. If someone at Logos will create the group (or authorize me to use the Logos name) I'll gladly help get some initial files available.
