I had some tweak ideas on the beta I'd love o discuss, but don't know what the protocol would be on he forums. Would it be permitted to talk about them in Fan Designs, or as a closed beta is that completely off limits?
Not a contributor, but I do participate in a number of BETA test programs. They all have a private discussion board or forum; was one ever set up for MW:D, or was this intended to be a fully open BETA?
If I follow what you're asking, the closest thing to a private discussion board for the MW:D Closed Beta is probably the comment threads on Update #40, which included the links to the PDF and the Google Form for feedback.
However, as I've said upthread, the results of that Google Form are what I'm using to collect, organize, and present feedback for developer and management review. While I assume you're free to post your thoughts here on the forums or wherever else, the Google Form is what I'm looking at. There's just too much other internet for me to try to collate each and every piece of feedback not submitted via the method management requested.
FWIW: Earlier this morning, we surpassed 250 individual submissions to that form - some people wrote one omnibus submission with all their feedback, some broke out their feedback with one note per submission, so it's much more than 250 individual notes. The feedback itself has run the full gamut of specificity (and usefulness) from very particular rules interactions that we hadn't thought of but do need to address, to "this system is trash, the end."
