Request: I believe this can be easily done but the problem is...

[romanticyao]

:cry: I do not know how :banana:

i've just bought and installed HiveMail on my website and have it integrated with my vbulletin.

so now my user will automatically have an e-mail account setup for them once they register on my forum with the same user name and password... that sounds great and that's really what i was dreaming.

But then i realize I am exposed to a huge problem!!! I am going to have a international forum where people from everywhere are welcome(mainly asians) probably they are going to use all different languages such as Chinese,Japanese,Korean ect. for their username.

As you all know e-mail address can only contain letter from alphabet and Arabic numerals, obviously none of those asian languages would work. for example,if one of my user register as ijij(username), then he will get a e-mail address like this: ijij@mysite.com, any e-mail address look like that is totally useless.

Here comes my request, can someone make me a hack that restricts usernames, so I can prevent my users have their username registered in different languages that contain illegal letters?

it would be easier if we limit the range...let's say,

first of all, no space is allowed, user can only register their username with following a to z, 0 to 9 and something else that can be used in e-mail address...

Please help, really painful problem :cross-eyed:
