WordPress MU

Hi there!

Are there any "real reason" why I should not allow users to register with only 3letters?

Tryed to change the code, like 3 places. And it all works to register with 3 letters after that. but are there any other stuff I should look into? Why is't set at 4? Any special reason?

Have searched but not found any reason?

None that I'm aware of. I know some *.tlds have a min legenth requirement but I don't think that would affect subdomains.

Aight, then I'll go for 3 characters instead.

Someone else that know of some problems?

Guess nothing is unfixible.

None that I'm aware, but I'm sure there's some sort of logic behind it.

I dropped Donncha an email.

It's a legacy thing - on WordPress.com we use languagecode.wordpress.com for different languages. Try es.wordpress.com to get the Spanish one. Since most language codes are 2 or 3 characters we set a minimum length on the username.

Change the limit on your own install if you like. It shouldn't break anything.

Dang, that was quick. :)

Nice to know Donncha. There's always "some" reason to it.

...and could you please give me a hint what files should I edit?

wp-includes/wpmu-functions.php

The check is in the wpmu_validate_user_signup function.

I tried but nothing happens...
I edited the "wpmu_validate_user_signup" function.
But still don't let the user register a blog with 2 carachters...

anyone can help ?
thanks.

I found the solution and it works in WPMU 1.2.4
Follow these steps and let wpmu works.

1) open the "wp-includes/wpmu-functions.php" (like drmike said)

2) In this function "wpmu_validate_blog_signup"
change the line number "1023"

if( strlen( $blog_id ) < 4 ) {
to
if( strlen( $blog_id ) < number_you_want ) {

3) In this function "wpmu_validate_user_signup"
change the line number "933"

if( strlen( $user_name ) < 4 ) {
to
if( strlen( $user_name ) < number_you_want ) {

Any trouble reply my comment.
:)
