I don't want to bother Bryght support with questions, so I will exploit this forum, so watch out... ;-)

We don't mind! As I mentioned earlier, we monitor the support forums closely, so go with what you're most comfortable with, either the forums or via email works for us!

I have found some gaps in Bryght's information which shakes my confidence a bit, but they've acknowledged that their working on a big site upgrade.

We welcome feedback on our documentation, since we're always striving to make both the service and the documentation better. Was there something specific you were looking for, or that wasn't clear or out of step with your experience?

This forum isn't active at all so why not use it for my newbie questions/problem?

It's true that most of the action on support.bryght.com is in the site administration forum, since most questions people have revolve around how to set up their site. We set this forum up (the "End users" forum, that is) as a place that people who were using the site to create content—as distinct from site administrators—could ask questions. There's a lot of overlap between site administrators and the people who create content and use the site, and I think since people see more activity at the "Site admin" forum, that's the most natural one to post to first.

My first trouble area, which I contacted Bryght support about but which I'm still confused with despite the reply, relates to setting up the area in User Profiles where users list their interests. I'm having trouble getting the tags in a linkable format, from just plain text. I will post on this next.

I think you're referring to the post about shared interests on user profiles, which I just added a reply to.
