I can put one in, if it seems needed. So far, there hasn't been too much call for that, but I can see it. I guess the question would be whether to have one forum, or sub-forums for different platforms, etc. Probably one forum to start with...
I don't think we need separate forum for this just yet.
I think it would be good to let the mix talk forum go a while then see where the distinctions are. If things become more PC/Mac/Analogue delineated then make them the markers, if things become DAW/Analogue delineated, break it up by DAW etc etc.
It's hard because many things can be used cross platform, and, software wise, some companies make things for multiple DAWS/platforms.
What about a thread discussing our favourite plugins to mix with? Gear and mixing are quite hard to separate but I do know where you are coming from - we could do without a ton of threads about "which _ to buy?"
If we just keep the Mix Talk forum to just that, mix talk, we can avoid the which to buy, x vs y, x > y flame war threads, but I think (and correct me if I am wrong John) you would still be able to discuss the plugs/gear that you use for mixing and how you use it - favourite or not
without any problems. For now I don't see a reason. If you disucss it in terms of mixing all good, if you want to do otherwise, then as stated before....
...there are already a gazillion recording-related sites with gear recommendations, etc.
But these are just my opinions and others' may be different.
