I seem to recall someone talking about a mod that automatically split the combat log text files, though for the life of me I can't find the post referring to it. I'm using LoggerHead to automatically enable /combatlog in certain zones, and several of my guildies are as well.

What I'd like to do is have the combatlogs automatically split when I log in, or daily upon login. The 20-30meg log files being sent around are not really feasible, and trying to get people to chop them up themselves is likely more trouble than it's worth.

Any suggestions?
