<p>BMRE Domain Monitor is built to keep an eye on the domains you add.</p>
<p>It checks the expiration date and warns you if a domain will expire in 30 days or less (both through email and in the admin interface)</p>
<p>It also has the feature (optional) to suggest domains that are similar to the ones you’ve added and that are still available.</p>
<p>DISCLAIMER: Do not ONLY trust this plugin for your domains. It works well but I can not be held responsible if something should go wrong and your domain does actually expire.</p>

BMRE Domain Monitor

This plugin is meant to monitor your domainnames and warn you before they expire.

<p>Checks Domain WHOIS Lookup for availability. Simple insert the [pwhois] shortcode on a page or post.<br />
To select the default TLD use the default attribute: [pwhois default=com] – sets .com as default in the TLD dropdown.<br />
TLD List is limited because of the knowledge of the required whois servers. If you wish to have support for a special TLD please contact me and I will implement it asap.<br />
We cannot guarantee that every domain lookup works perfect, in case that whois servers and how to talk to them can change time by time.<br />
However if you inform us about changes and we can get it to work, we give you a free version of the Pro version of this plugin!</p>

Powie's WHOIS Domain Check

Not what I needed. It can only check availability for .com domains, not any TLD as in description. One star for inaccurate description.

LIMITED – only checks .com
