Apparently a username has to include NO spaces. However, some of our customers have said they can't set up a username and when I ask them if it had any spaces, they say it did.

So my question is, whereabouts in the formatting is the option to put a little sentence beside USERNAME when someone sets up a profile, just telling them that it must not contain any spaces.

I only want this to show up in the register option, when they are filling in their details.


Thanks in advance.
