It was def available... in the iM vs X match there's one vid that Buffy took as an observer and someone from /X/ said something like "you should hear our rw" (roger wilco) - so it was def available.
It's come a long way since then of course and people still often typed things anyway... I'm sure I typed more that I voice chatted back then. A lot of people prob didn't even have a mic.
Now if anyone has any suggestions on a few things regarding fixing a T2 high res hud... health/energy bars are quite tiny, as is the objective/score hud... anything which could help make the demos a bit better in regards to being able to see what the score is or how low the recording players health is would be helpful.
EDIT - fixed the score hud issue - found a script and edited it to suit my purposes, it's not perfect but it's much better than it was. In the the finishing stages of uploading a demo now so it'll be there from the next one onward. Health/Energy bar still tiny though.
