Okay, I screwed up a little. Today I've submitted a number of factors without being logged in.
If you take a look on your score card I think you'll find they're already sorted.

For any factors where the user wasn't logged in, I check the sieve and P-1 reservations, and match them up that way automatically. So usually you'll only see them as [unknown] if I'm a bit behind on updating my copies of the reservations.

If you can't see your factors, give me a shout and I'll have a deeper look.
