DISCLAIMER!
I know this is not World of Warcraft but 99% of users who play WoW use vent so I thought i would add this here. Also, this does not work on 100% of the vents but it should work for the majority of them. Lastly, this will only work on guests. Which is perfect because most people are guests when they join a random pug, arena, or a guild vent. Use at your own risk.
Ok, this is what you are going to do:
1. You have to enable your vent to allow it to open up multiple clients at one time. To do this, simply right click your ventrilo icon on your desk top and click "PROPERTIES". Then, where it says "TARGET", you want to add a space and -m.
So it would look something like
"C:\pgrm\ventexe" -m
alright. Second step.
Now to the meat:
with your first vent you want to log on the server and scope out the person you want to kick from vent. Once you have his name, open up your second vent and create a user with the exact same name. Once you're done, just click join and watch as he gets kicked for having a duplicate name!!
There you have it! How to kick noobs from vent without being admin! . Have fun and don't abuse it (too much)
