i think we should have in-match reporting. it could add excitement to the forum and provide a valuable service to those who cant watch the match or would like a play by play summary from a forumer's perspective. reading post match threads are boring since all they ever say is "good job" "i knew it" etc.
it should be in general messages because thats where most of us hang out. so then itd be like listening to the radio when reading a thread. i hope you seriously consider it.
The problem with allowing those in GM is that everyone will "migrate" to GM during the match and leave the tournament forum (which actually serves this purpose) empty.
In-match reporting can be found in the live score threads, if you just manage to dodge the gamblers cursing, you'll get a good perception of what's going on in the match. Some kind posters even provide a point-by-point live score.
As for the post-match threads in GM, I know it's full of posts saying "good job", "well done", etc., but there are always posters, albeit in a smaller number, who write a small summary of the match. It's just a matter of skimming through the thread and you'll find them.
