This may be considered double-posting, but in my defense, it's been 17 hours since I last posted...
Are reserved slots handled by a mod, or is it built in to TF2?
Due to the recently flub at The Planet, which hosts VGMusic's server, we may have substantially more bandwidth there than we used to (2.5TB instead of 1TB)... so I was thinking of setting up a game server there. Possibly TF2, possibly something else (HL2 deathmatch?), but I'm not sure how Source servers handle reserved slots.
