For us I think a melee kill, C4 kill and kill streaks would be a good start. You don't want it to be too zealous about every single kill. A T-Bag detector would be good too!
We seem to be getting more people on the server the last few days and it even got started on it's own too. A few of them seem to be returning too.
The smaller map size is fine once you get used to them and realise that a couple of flags are missing but the only annoying thing is that the bases don't get moved but that is a game thing and not to do with the server.
Just wonder if the map order could be juggled a bit? Though it sometimes gets changed because of the next map vote, quite often you miss the vote because you have just been dip, dipped, or killed by yet another clay ( you know who you are

). The result is a lot of the maps further down in the list never get seen. Any order will become familiar so may be a little swap around every so often might help it stop becoming stale.
