Archive feature #15
Description
I see your planning to implement the archive from npfchan. I just have one word: Don't.
Make the archive a flag in the posts_* databases, doing which, you can restore a thread for whatever reasons, view history and anything a post alive-dead can do.
The index of said archive could be a board index or catalog.
If you do so, do not copy the index. Nobody likes to stare at lists with short description to try to find a thread.
