Any chance you might start a forum on Toon Boom or TVPaint or just a general 2D animation forum? I've been searching the net for days trying to find info about the best 2D programs and if you had a forum here, I'm sure all the info would be here too.
We have tried to launch a ToonBoom forum more than once and each time the forum has drawn no traffic and no posts. So we turned them off. We do not like to keep forums active that are not meeting our minimum standard for inclusion in Creative COW.
We have a Motion Graphics forum and maybe it's time to set a rollover link from 2D Animation to that forum. The Motion Graphics forum is the one that I think you are most likely to find some discussion on the topic you seek.
In the meantime, here are the references I found to ToonBoom by using our search engine here in Creative COW...
