Adding Tags to a Project ?

I think at the moment only curators can add tags (until the feature is up and running properly) I may be wrong but that is my understanding.

what a pity, for that makes me again dependant of others while I am elevated enough to do so myself....

My understanding is that it's just while the feature is being introduced so please have some patience.

If you collaborate on the project, click the edit link near the top and you can add tags there. We are going to move it to a better spot in the next release.
