For WordPress Multisite (WPMU) installs, allows Super Admins to easily manage each users roles and blogs from one 
screen in the Network Admin menu.
You no longer have to go to each blog to change the user’s role. It’s also 
much easier to see which sites a user is associated with.

Multisite User Role Manager

Ajax management makes it super easy to add users to a bunch of sites in the network. Does 1 things really well, more plugins should work like this.

Great for multisite user management

Made adding a user to 20 sites a lot easier than using WP's default interface for that (way less clicking around).

Much easier to assign a user to many sites

I spent about 30 minutes looking at different multisite user management plugins and all of them were either out of date, or tried to do too much. This plugin solved the exact issue I was dealing with: adding a user (with a specified role) to all of my client's subsites. 

Thank you very much. 

I wish you all the best,
Kevin.

P.S. the CSS for the admin screen where you add users to subsites was a bit off for me (in Chrome). The table did not fit the modal background (it hung off to the right a bit, and forced me to scroll even though there was plenty of vertical space). It doesn't bother me but it might bother some other users so I figured I would let you know. 

Excellent plugin - it does what it says!

This plugin allows you to set expiry dates for user logins. You can set a user to:
<ul>
<li>Never expire (default)</li>
<li>Expire in X days, weeks, moths or years</li>
<li>Expire on a specific date</li>
</ul>
When a user expires you can:
<ul>
<li>Change the role of that user</li>
<li>Replace the user’s password with a randomly generated one</li>
<li>Send an email notification to the user</li>
<li>Send an email notification to the site administrator</li>
<li>Remove expiry details and allow user to continue to login</li>
<li>Perform you own actions using an <a href="https://github.com/benhuson/expire-users/wiki/expire_users_expired" rel="nofollow ugc"><code>expire_users_expired</code></a> hook</li>
</ul>
You can automatically assign expiry details to users who sign up via the register form.
The email notification messages can be configured in the admin settings.
