I had the problem that I wanted to limit the possible usernames to a special set of characters - a regular expression.
Vb has only a function to disallow special characters, but this is not what I need, I wanted to have the first character is a char, other characters are char or numeric and the only special chars are "-" and "_".
Here is my solution I want to share with you:
Open register.php
find:
if (preg_match('/(?<!&#[0-9]{3}|&#[0-9]{4}|&#[0-9]{5});/', $_POST['username']))
replace with:
if (!preg_match('/^([a-zA-Z][a-zA-Z0-9-_]*)$/', $_POST['username']))
Change the phrase "username_semicolon" to an appropriate text.
That it ;)
I don't want to give support for this hack, because most question will probably be about regex and I'm not a regex-guru ;) and I don't think that there is any need for support - but I'll watch this thread.

EDIT:
I don't believe it - I've searched for a solution this morning, couldn't find anything and produced this hack - and now, a half hour ago Reynaldovb also released a very similiar hack here: https://vborg.vbsupport.ru/showthread.php?threadid=73559.
I didn't know about the thread he mentioned.
So please choose which hack meets your need best.
