Highlight a phrase using your cursor, and click the bookmarklet (first drag it to your bookmarks to install).
A new window will open showing you availability or ownership info. It will remove the spaces and tack on .com
If you have not highlighted any text, it will check the domain name of any website that you are currently on for ownership information by doing a whois lookup on Ultimate Domains, in a new tab!
Since this opens a new window, you may have to add UltimateDomains.com to your popup blocker allowed sites list (whitelist).
An alternative way to add this to your bookmarks is by right-clicking it and selecting "Add to bookmarks".
Drag this bookmarklet to your favorites tabs. Click it when you want to check the whois of a domain or check a multi word phrase for availability.
