In order for our SMF integration plugin to work better for existing SMF logins, I have in aMember > Admin > Setup, set valid usernames to allow capital letters (no auto-conversion to lower case) as well as spaces, as some of our existing SMF usernames utilize both caps and spaces. However, in the sign-up sheet, it still says "may only contain small letters, numbers, and the underscore '_'", which is inconsistent with my configuration. It seems like the configuration should be recognized and it should say "Lower and upper case, numbers, interior spaces and underscores are allowed" or something like that. I was able to edit _TPL_SIGNUP_LOGIN_ in en.php. Is that the best thing to do?
