Any thoughts on this #bug-reports and #curators? I have 10 UCB interns waiting to interact on each other’s projects but can’t seem to make the group due to this error.

(Those hashtags just reference the forum categories, they don’t notify anyone.)

It looks like you have 4 of the 5 projects successfully attached to your umbrella project. Is the problem that you can’t connect the Strawberry Creek one? Or something else?

@hydrocycler mind if i try? As a staff member I can edit projects.
