First let me apologize for the threads that were lost when the site ran out of disk space. We haven't lost any threads in a very long time, and I'm taking mesaures to insure that this doesn't happen again.
Unfortunately the lost data cannot be restored. I make periodic backups of the entire site, but the last one was a couple weeks ago.
If anyone would like to resume the discussion of a lost thread, please submit a thread proposal and I will promote it as quickly as possible. Give it a title as best as you remember, note that it is for a lost thread, then briefly summarize the discussion.
