I just upgraded SB's Primenet server to allow for in-client un-reserving.

It's a small tweak in some ways but every little bit helps. This means if someone uses the "Quit GIMPS" option it will at least un-reserve their tests right away instead of 30 days after the last report.

And I think the client may unreserve tests on it's own from time to time in other situations like when it falls behind.

The website's un-reserve page in the "Preferences" section will still work too if you need it during testing.

Hope this helps.

Cheers,
Louie
