Thanks Guys. They can already do that. Not really as they don't get anything except the $1 which they would receive anyways. I don't know. Thanks, and I don't know.
I've already made this suggestion awhile ago but Support! http://www.mineverse.com/threads/new-kitpvp-kill-streaks.98045/
I support this suggestion. I think it would be pretty cool and it would tell you who the better PvPers are, as long as it's not some diamond kill-farming /kit fights. I probably wouldn't end up with too high of a streak - haha.
