In the 2142 server list you can see all these icons. I guess they are generally the same as with BF2. What do each one mean (sorry if too small, real size copy)?

First 1 offcourse BF2142
Second is sort of server
Third is that you can use your mic
The other one is about punkbuster
The rest± no idea.
The '+' is to add the server to your favourites.
The 'i' is to give you some server info, e.g. current players, current map, IP address, etc.
