Thanks for building this, looks nice.
I think the data doesn't get saved if you fill out the form partially and save it as draft and reopen it later? I'm not sure here, but I think I filled half of the fields this afternoon then I had to stop what I was doing and I saved as draft, and they're all empty now. I might have clicked something without thinking though.
Then while I was messing around the form the site stopped responding and went unreachable for a short while ;3; I hope I haven't done anything that made it go boom X°
Also, a few issues with usability/documentation.
The site guide in the policy says a thing about using relevant taxonomy and not create ridiculous ones, which would be perfectly good except it doesn't make sense in the current user interface... because as far as I can see we are bound to use the taxonomies we are provided as-is, and we can't create new ones, and not even add new options to the already existing ones.
Which leads to another issue, shouldn't the Origin Countries taxonomy have an "Other" option, like the "Languages" one?
I can't find that thing listed the Profile guide... so what is it? The creator's nationalities or the UTAU's nationalities? Sometimes they can differ.
-- edit --
yet another thing... I was trying to add a voicebank to a profile, but when I click "Add New Voicebank" on the bottom of the profile form I just get a little spinning thingie that keeps spinning forever and does nothing. I also can't associate the VB to the profile the other way 'round (from the voicebank page), it keeps showing the spinning orange thingie and does nothing.
In case it's relevant (and it probably is...), I tried with Firefox/Linux and Chromium/Linux, same thing in both cases.
I also don't think it's safe to show all the listed UTAUs when you're associating a voicebank to a profile ^^; I think it should filter only the profiles you own... besides security, if the UTAU directory becomes huge... well... it's going to be pretty hard with that dropdown field.
