Mini Mods - Restrict usernames to alphanumeric and underscore

This is a vB 3.7 port of the same mini mod.
( https://vborg.vbsupport.ru/showthread.php?t=73559 )

What is this Plugin about?

Are you tired of seeing in your forums usernames like these?:
1.- The Super Boy (spaces)
2.- my_new_name (underscore abuse)
3.- im?a??nd?b?ar (international characters)

Well, with this simple addon you can prevent that from happening from now on (it can't correct already spoiled usernames). When a user tries to register using one of those chars, a nice error message makes sure the user picks another "normal" name.

Installation instructions
1.- Download the attached .xml
2.- Go to Admin Control Panel => Plugin System => Manage Products => Add/Import Product => and browse for the the location where you downloaded the .xml
3.- Hit Import
4.- To configure it (not really needed, but it is there), go to Vbulletin Forum Options => Restrict Usernames on registration

By default this addon prevents spaces and any char other than numbers and (english) letters while allowing underscore.

**Disclaimer**
This mod is not absolutely necessary as vBulletin allows you to do what this mod does and more from within the Admin Panel:
Admin CP -> vBulletin Options -> vBulletin Options -> User Registration Options -> Username Regular Expression

You only need to use this mod if you don't want to deal with Regular Expressions.

No. By using RegEx inside vB ACP you have a lot more power restricting what you want and what you don't want (it says that on the disclaimer). This mod just makes it easier and safer and people were asking for a port to 3.7

"By default spaces are not allowed."

Is this worded intentionally? It'd be simpler if it just said, By default spaces are allowed instead.

I only ask because the variable name says: "ru_allowspace", hence the confusion on the title.

THanks for the mod though, sometimes it's nice to have things like this than mess with the dreadful regex :P

I tried this and installed it and appeared to be working, but i was able to register with a space, regardless of which option it was on.

Uninstalled.
