About pools

I have a problem when I try to upload a pic in a pool. When I use the "add pool" command it only appears one (http://img511.imageshack.us/img511/9669/01gd8.jpg)
The only way I can do this is importing them from the pool menu, but I have to create a new tag so I don't import like 20 pics.
Is this a problem with firefox, only me or it happens to someone else? (by the way, I prefer the old way to do this...)

Which pool are you trying to add it to?

I haven't figured that out either.

I've added two pics to the "missing thumbnail" pool (using the import option and creating a new tag so no others pics are selected).
This problem happens to me before with another pool (鈴仙因幡ウドンゲイン - Reisen Inaba Udon-gein) so I think is a problem with the system or something like that.
Basically, I can't choose the pool in that new menu or they simple don't appear.

Try now. Pools have to be marked as active in order for them to show up in the listing. I pessimistically set everything as inactive when I made this recent change.

Apparently it works now, but it's normal that only those four pools pop-up from the menu (http://img76.imageshack.us/img76/338/01ha3.jpg)?

(I can't delete my comments on the forum?)

I only have Missing image, Missing Thumbnail and The Art Of Pop
