Hi folks, I'm making this sticky just to let you all know you're not going mad - and neither is the zoo - if any of the following happen.
If your problem/question isn't here, please put it in the
Comments on the Galaxy Zoo 2 thread, or start a thread on this board or in Technical Support if it's a computer problem. Thank you!
Q: I just got asked to compare a galaxy to itself in Galaxy Wars!
A: It's a bug, and we know about it. But there's so much else to do with the site at the moment that it's not Number 1 on the list to fix! Please just click either galaxy at random, and think of it as an armistice
Q: I got asked to compare the prominence of a bar/spiral arms to a galaxy which doesn't have those things. Is this an error?Not really. The selection is random. We're trying to arrange galaxies along a continuum of bar/spiral arm prominences, but there are too many galaxies for us to plan it all in advance.Q: I can't see the Object ID of the galaxy. How can I find out more?Sorry, you can't. This was a conscious decision. Please see here for more.Q: In "My Galaxies", it's got my last galaxy down twice or three times! Why is that? Does that mean it's wiped out some of my other classifications?Not at all. The "Galaxy Wars" bit counts as a separate classification. 
Please send me suggestions for what else should go in this thread!
