Thanks. When you've messed stuff up as often as I have, you HAVE to get a little better at debugging...
I've been avoiding nested quotes since I determined that was (?) the problem. I'll try it again and post back here to let you know.
Shawn, I just posted a reply with a nested quote using the Quick Reply feature and it worked flawlessly. Looks like they got whatever that bug was.
Not sure if this has been mentioned before, it might be another bug. Custom User Title seem to revert back to their defaults - except for a few http://forums.digitalpoint.com/showthread.php?t=20065&page=2
Hmmm... if you stop using a custom user title, does it go back to Peon? Looks like it might be a reported bug now that I look it up in their bug tracker... http://www.vbulletin.com/forum/bugs35.php?do=view&bugid=599
wwwhomes, nevets and tops I noticed going to peon not their respective 'ranks' - for most they have reverted properly (see mella). Just to confuse you, I set mine to peon again.
Well as I said, it looks like a bug that might be affecting beta 3 (was reported initially by a vBulletin developer). So probably pointless to rebuild all the user titles at this point. I'll rebuild them when it's fixed.
