Suggestion: Feature Request threads for each software forum
I think you should have a thread in each forum for feature suggestions for that software. I realise that just requesting a feature is no guarantee that the software developers will add it, but if you're going to have official forums, this seems an obvious addition.
It would be best if you could create your feature request topic in the respective product category and tag it with feature-request.
Please refer to FAQ: Are post tags really helpful? How do I use them? regarding how to do that.
