Ok, let me answer some questions!
We'll feature as many RPs in each Digest as we get summaries submitted. If you don't want to submit every week, you don't have to -- it's not like you'll lose your spot, or anything. Just send in an update when you feel it's appropriate.
I think that for the first one, just a general "here's what's going on" will be appropriate. If that takes a bit more than 100 words, that's ok, but I don't want novels, people! The digest can't be 50 pages long, or it defeats the purpose.
No images at this time, sorry. Perhaps in the future.
Also, the first Digest will be running on August 3rd. Some people have already sent in summaries -- unless you want that to be your first submission (and I'm fine with that) -- I suggest you resubmit a summary by this coming Sunday, August 2nd.
