How do you limit username length

[dilaca]

Can someone please tell me how to restrict the length of usernames? 

I can only find the option to limit characters in signatures.

Thanks.

Currently, there's no setting to limit their length.  However, you can go to:

Themes/yourtheme/Profile.template.php (if it doesn't exist, copy it from default...)

And find the following:

<td><input type="text" name="realName" size="30" value="', $context['member']['name'], '" /></td>

Replace that with:

<td><input type="text" name="realName" size="30" maxlength="LENGTH HERE" value="', $context['member']['name'], '" /></td>
