Don't get me wrong -- I'm not complaining about anything per se. But maybe the project pages should add something about the "projects" & "templates" tags when discussing which tags a person should follow when joining a project. Something like:
"If you are interested in discussions about overall project topics -- topics that affect multiple projects -- consider adding PROJECTS to your list of followed tags."
Or:
"If you are interested in discussions about the contents & display of the templates for this and other projects, consider adding TEMPLATES to your list of followed tags."
If I'd ever seen something like that, I probably would have added one or both tags to my list, & then I wouldn't have been so surprised when the boxes changed. I probably also would have joined the prior discussion, or at least followed it so I knew what was going on.
