Sadly it isn't used much by myself or other {dFb} members that I'm aware off but I hate to see a perfectly good server go to wait either.  That is in part ot the fact we just don't have enough UT99 members and 3 {dFb} servers ATM.

That being the 2 GhostHouse servers (NewYork and Texas) and ofcourse the freestyle server. The GhostHouse seem to generate a fair amount of traffic. I think alot off people like the team base only format. I've recently put JailBreak back on the freestyle server but I admit I use my time for the GH more just becase that's where people play and so far I havne't seen alot of traffic on the {dFb} Freestyle
The fact that your thinking of putting it in Chicago is kind of cool as it's seems smack down in the middle  and that would kind of cover the country quite well for ping.

The GhostHouse Format is a hit so far, perhaps we can try this on the freestyle server as well  or introduce a DM only GhostHouse format. Any Ideas are welcome.
