Page URL incorrectly states username is when it contains a period/invalid character
LinkStack version
4.8.0
Description
When selecting a username on the Sign Up page, the text field for Page URL will erroneously report that a username is taken when it actually contains an invalid character (such as period/.) on the main LinkStack instance.
Details about your system
Linux/Manjaro Unstable with Brave Browser version 1.66.115-1 on the main LinkStack instance linksta.cc.
How to reproduce
Suppose multipartusername is the desired base form of the username and is not taken.
Using a pure alphanumeric multipartusername, hyphen separators like multi-part-username, or underscore separators like multi_part_username is valid.
However, multipart.username is invalid, since periods are not allowed. However, the form reports with client-side form message that says:
That username is already taken
Possible Solution
During the sign up process, if an invalid character is used for a username, then the form should tell the user that an invalid character has been used; and also the user should be told what characters are valid in usernames.

This system will be replaced in the next major revision.
Until then this will be the intended behavior.
