Is there any restriction rules for username (login) in PieRegister?
If not, please add it.
Such as: min/max characters, acceptable symbols (Cyrillic, Latin), certain symbols (@,#,* ), characters with accent (é û), email as username, spaces in username, part of user login (or login), only numbers.
Special characters and spaces are not allowed for username field while user register from PR registration form. Other than that we will consider your request in our future release. Thanks for writing down to us.
