I normally like GitLab issues as a place for bug reports.
A FAQ and an old style forum works pretty well for help.
In fact, just make a community on Lemmy for the forum part and you’ll have what’s required.
GitHub also has this new “Discussions” thing which should do some good, for those that want to stay on GitHub
It would make a lot of sense to the company trying to decide how large their production run should be.
For the customer, it only really makes sense if they are getting something out of it, like immunity to possible price hikes at launch.
I don’t pre-order, but then, I am a late stage buyer, so it doesn’t really apply to me.
