I discovered some issues with the new forum system... In particular it seems like the printing functions are broken (everyone gets an "access denied" type of error when trying to print a thread). Send to news article function has been removed or disabled. Also, converting a thread to PDF format is now a lot more awkward. Rather than clicking on a PDF icon next to a post, one needs to click through several screens to get to a PDF version of the thread. Finally, the highlighted/unread issue was only partially solved; if one goes directly to the root of the forum after posting (or to a forum section other than the one they just posted in), the post they just made will appear as "unread".

Uggghhhh.... Well, since the old system will no longer be maintained by XOOPS developers, I guess upgrading to CBB won't hurt. Hopefully all of these silly issues will be addressed by the developers eventually.
