Please add something to allow the server host to switch change people to other teams, and alter team colors from the get go.  I wouldn't suggest administrative powers like kick/ban because there's really no reason.

I start a server now and then and someone is intend of having their team color green or something, we start and it shows up as blue vs blue.

There were some team color and assignment bugs that are fixed in the next update. See if it is any better once that goes live. Watch the sticky thread about "Known Issues" to see what is fixed in each version.

As a player I'd really like to be able to switch spots with a bot on the other team at any time.  Winning 36-6 really isn't fun and I like to switch teams in other games like TF2 and see if I can make the different and help that team come back.
