Not sure why we arn't showing up in the browser, it could be because of the type of game that is running on the server at the time.. For example if BunnyTracks is running it prolly won't show up if your looking for it under deathmatch or something.

As for the map vote.. Goto your Undeal Tournament system folder and find the file USER.ini open that up and find a key that doesn't have anything assigned to it.

For example: I use the M=

Put this next to it: 
mutate bdbmapvote votemenu

so it looks like this:
M=mutate bdbmapvote votemenu

Hope this helps. Feel free to hop on TeamSpeak if you need more help or just want to hang out!
