I think, that it would make the forums more clear, creating a third group of forums:
GENERAL - Official Announcements
- Other Arduino Talk
- General Electronics
- Off-Topic
The Digispark (and perhaps soon the PRO) - Digispark Support
- Digispark Libraries
- Digispark Projects
- Digispark Project Ideas
The DigiX- DigiX Support
- DigiX Libraries
- DigiX Projects
- DigiX Project Ideas
That way I think, it would become more clear, where to post, as all products would have their own sub-forum group.
