Chris,
The merge into lost threads and all other functions within that option need updating. I made a lot of table structure changes without changing this function. It was low on my priority list as I don't use it

I willl get it fixed though.
As for a news feed, I switched to onlynews.com from newsfeeds. They are very fast and have no speed restriction, but the retention is pretty crap (4-5 days) and the number groups is quite low. I'm looking for another one myself. Let me know if you find one.
mobilebbs,
There are several reasons why posts may not get imported.
1) You haven't corrrectly mapped the local forum to the usenet group.
2) The article numbers have somehow got out of synch. (try resetting the numbers to zero for those groups)
3) you are pulling historical posts and have autopurge turned on and set too low. This will cause old posts to be immediately deleted after being imported.
4) The articles are all getting rejected for spam (unlikely)
