hello,
i tried to create a regular expression wich doesn't allow new users to create a username with a "." in it.
I tried too, but it doesn't work - even if it does in "regex coach".
Is there a special CommunityBuilder RegExp semantic or something like that i have to know?
It would be nice if anybody could help.
I do need an expression for usernames wich allows: a-z, A-Z, 0-9, - and _ (wich should be included in a-z - i think so)
points "." and any other symbols should be forbidden.
sound very simple - but as i said - couln't get it to work.
yours pedda
