Add a Thesaurus or Suggested Similar Words

I'd love to be able to quickly access a thesaurus on the site. I'm always looking for alternate words when my first name idea is taken. Maybe even suggesting similar words.

eg. a search for fastfood.com might be taken but you could get similar words like
fast - quick, rapid, snappy
food - bite, snack, chow

Which may lead you to search for "snappybites" which isn't taken but has a similar meaning
