I forgot that I wasn't allowed to use "-" in the name when I set up the site. I'll have to search the feature requests/updates to see if dashes are/will be allowed (after the other bit is sorted).
Yeah, there currently are no plans to add support for dashes in subdomains.
As for your application submission issues, I've gone ahead and lowered the restrictions for the verification image (not requiring case sensitivity). The verification image will show between 3 and 5 characters, so it's no biggy if it's quite small - that's normal.
I suspect a lot of the problem had to do with the case sensitivity of it (since most CAPTCHAS don't require case sensitivity).
Let me know if you users are still having the problem. I was able to submit apps on your site fine from both IE and Firefox.
Thank you, Chops. I will put the word out to have them try again, and tell me which browser they are using as well.
Now that the weekend is over, it may take a few days to get many responses. However, since I couldn't replicate the issue myself, I suspect there's a really good chance you've nailed it.
