I'll move this to Feedback, btw.
For some reason I thought we had one, but I've double checked and you're right - we're missing one.
Normally, I'd look for existing discussions and then look to set up a new board to cover them.
However, we moved to a completely different forum software platform a few weeks ago, and unfortunately the tools I need to do that properly are not built into this version - but are present in the next update, which should be released within a few weeks.
After I do the update, I'll look for existing discussions, and see whether we have enough to justify a dedicated board. That's our criteria for all our author forums - they are simply set up to accommodate existing discussions, and thus make them easier to find.
