You are right...
The similar threads are being updated properly, because if you browse the newsgroup posts, the similar threads show up, but sure enough, the search index isn't being updated properly, even though the function (
build_post_index($postid,$foruminfo);) is being called in gateway.php
Also, the update is not working for me at all... I have tested it on several posts, and they are not being sent back to the newsgroup. (see prior posts)
I love the functionality, and would like to see the original author come back around with a new version for vB 3 Gold...
I'm fine with any PHP, but I'm not sure about the interaction with the NNTP server, and how all that works well enough to really re-write this...
I would also enjoy seeing a control panel section for this hack... with lots of options!
