On a multisite installation, the admin bar has a menu item called My Sites.
If you’re not a big fan of the admin bar on the front-end, try this widget instead. If the user is not logged in, he won’t see the widget at all.

My Sites Widget

A widget that displays a list of sites that the current user has access to.

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).
