Frequently Asked Questions

Common questions about Restrict Usernames

No. The plugin only prevents the usernames visitors can use when registering for an account. An admin that has user creation privileges can still create a user account, from within the admin, using any otherwise valid username. Username restrictions don't apply to admins.
No.
Yes.
Nothing happens to those accounts. The plugin does not do anything with existing accounts. Existing usernames are not checked against any username restriction rules; that only happens for accounts being newly registered on the front-end.
No. A future version will likely add a way for you to optionallly specify a message to be displayed to those registering for a user account.
No. A generic "ERROR: This username is invalid. Please choose another." is reported.
Most likely not. Many membership plugins implement their own user registration handling that often bypasses checks (and hooks) performed by WordPress. As such, it is unlikely that the plugin is compatible with them without special plugin-specific amendments.
Yes.
Yes, for at least BuddyPress 1.2+ through 2.6+, and perhaps other versions.
Yes.
