Also what about handling banned users?

I do see a "Ban User" function in the admincp with a length of time to select. It is definitely possible to ban a user in TS3 for a certain amount of time that would be equivalent to their ban length on the forum. Problem is, again, there are no hooks in the ban user script for vBulletin. :(
I like the idea though and I'll definitely work on seeing if there's another way.

Hmm what about if banned via the warning system?

Also when a user changes usergroup via the user cp with permission groups.

Does someone have this running live. I'd like to check it out.

We are running it but its for guild mates only. I can say this it works great it just needs a couple more features so its more automated. The admin interface could be better but it works. Run run our own teamspeak server off our dedicated server and it has no trouble interfacing with our server.

we are running it on our server, as the developer is in our team :-p

you are welcome to come see it in action if you want. Rush is the one who made it (whatpulse here). ts3: voice.teampulverize.com:9987
website: teampulverize.com

i wont be around until sunday night though.

Post any other loose ends you can think of, I'm going to put out a big update next with everything and vbExperience support when the vbExperience dev fixes something.

Instead of disabling the hook could you check for duplicate unique id's in the DB when submitting?

Edit: NM. I guess my server provider doesn't allow a permission that this script requires.
