Actually, Tarv, this is a common thing. There are numerous log parser programs that can take that log info and track loot, damage taken/dealt, skills advancements, etc. This also include a db of all /tell /say /gsay etc.
I use one from time to time. I tis nice to be able to go back and review situations...especially where things go bad. Sometimes you can see things that people said that got missed in the ehat of battle that can baetter clarify the reasons for the problem. Kind of a tactic and strategy analysis tool.
