I saw "Universe@Home" on the "Sign-up for projects" page. I then used the "Create Account" paperclip icon to sign up for that project. And I saw it fade out, such that it is now correctly not listed on that page.

HOWEVER:
When I go to the "My projects" page, I do NOT see it listed at all! It should be listed here, right? Can you look at the code for this page, to see how it might somehow not list the "Universe@Home" project?

Note 1: I had previously signed up for "Universe@Home Test" project, and want to continue staying signed up for it. So, I expect to see both "Universe@Home Test" and "Universe@Home", on my "My projects" page.
Note 2: Oddly enough, the project does show up on the Host list's list of projects. Just not on "My projects" for some reason. Bug.
Note 3: This might be related to this issue -- Seeing this whenever BOINC tries to process a BOINCstats change for the project:

How can we get this fixed?

"Universe@Home Test"

"Universe@Home":

No problems today for me when joining this project. Both Universe projects are listed at the usual places, no errors in the communication of BAM! with the host.
I guess Willy was probably introducing the project at this website when you joined yesterday...

Yeah, it is working correctly too for me now. Thanks for fixing it Willy
