Looking to see where to change the minimum requirement of 4 letter subdomains when users sign up....
I would say that inside wpmu-functions.php there are several instances where they are giving errors for <4 for the ID, so, I would bet if you changed all the <4 to <3 that pertain to id, you would get your desired result.
I have a two letter subdomain, and didn't have to change anything to get it. What version of MU are you running?
