Stats was a pain in the ass to get setup. I don't think ILAN is really into doing them, its not much of a money maker.
Send a email to jill@ilangame.com and let her know you want stats added to your server. It cost $5/month.
It took forever with ours because they ran into a lot of problems. Hopefully they figured out how to do them and it won't take so long for yours. Part of the problem is the stats program wans't made for MOHAA.
After they get it set up it's all automatic. One thing to keep in mind is if you restart your server. A new log file is started so stats are only from the last time you restated your server.
You may want to remind them to add
(+set developer 1) to the command line, that was part of the problem with mine.
Rember you can always point people to
FK's MOD Comparison to get all the facts about his mod and how it compares to others.
