Looks like all 5 of mine failed, even though they charged my credit card. Just got the "we're sorry but the domain failed to process" emails. Thanks godaddy!
Hopefully it goes through. Same thing happened to me, only instead of a confirmation email I got an email saying the domain was actually already taken. curses.
Also got another 11 three-letters, and one four-letter. Looks like the frenzy has died down by now, godaddy is slow but all my domains processed right away.
One annoying thing is godaddy stopped accepting coupons for .me domains halfway through... so I didn't get any discounts for the last few. Ah well.
After that I tried like 6 times to register, and out of like 70 domains I "got" only 5 went through. I did get a hold placed on my credit card because of suspicious activity because of this.
The 3,3 means 3 characters minimum (anything less is invalid) and 3 maximum. So increase that second number to get more words.
