When users are first created, they are automatically assigned to the primary blog. But, you may want to set them up on multiple blogs by default. This is especially helpful if you’re using bbpress or other forum software where the user needs a role on that blog in order to participate. This plugin allows site admins to set the default role on as many blogs as desired for all new users.

WPMU Default User Role

Lets site admins define which blogs a user should automatically become a member of, and with what role. Multiple blogs supported.

By default, WordPress network usernames cannot contain anything but lowercase letters and numbers. This plugin adds network options to let you include hyphens, underscores, or uppercase letters, if desired.
Furthermore, this plugin gives you the option to allow email addresses as usernames, or to allow all-numeric usernames (e.g. “1234”).
Finally, this plugin lets you override the minimum length for usernames (which defaults to four characters).
