Requesting MOD

Is there a way to putt extra information by the users. A nice example of what i mean is the forum of XDA-Developers.com. They have a extra option to show your device, country and network. I would like the same thing for our forum butt have no idea how to do such a thing.

I can't find a MOD that does this butt maybe i didn't look in the right places. Little bit of help would be very nice.
