There's lots of stuff on Community Pricing. Some of it's been there for a long time Many of us have bids on resources in Community Pricing that we really value very highly and wish were in our libraries yesterday. Often we say as much in threads devoted to those resources that are ignored by people who've decided from the thread title that they already don't care, which limits our ability to mobilize support for stuff stuck in CP. My hope is that this thread title should get around a lot of that.
So why should I put in a bid for your favourites? I'm already sold on mine. What's valuable in CP that I might not have a bid in for? Why is it valuable?
For the purposes of this thread, please follow these guidelines when posting:
1. Please use at least two hundred words per book/collection to explain why something is valuable, not including any excerpts or quotations from the book or from the product page. "Buy x, it's awesome because it's a great {genre of x} book," and "Buy x because y wrote it (and you already know that y is awesome)," posts are not the point of this thread. The word minimum exists in order to make posts in this thread more useful to readers than otherwise.
2. No more than one CP offering per post, in order to avoid reader confusion.
3. No more than two posts by the same person in a row, in order to avoid thread monopolization, but there is no limit to how many offerings one person can promote.
4. Don't write about why some resource is not valuable.
5. Remember that something being cheap is not a reason why it's valuable, although if it has some value, it being cheap might make buying it worth it.
6. It's perfectly fine to promote an offering that someone else has already promoted, but their words don't count toward your two hundred.
7. Please remember to include a working link to the product you want us to bid on. 
Thanks! Let's see if we can give some CP resources a boost.
PS: This post itself is almost 400 words, so 200 should be a breeze.
