Hi Rob, I have just seen your comment above, and am reaching out to you privately to figure out what happened and to see what I can do. Searches aren't kept around at all and I can assure you it's not the goal of Namevine to register domains/handles that users have worked hard to find.
How many historical searches were you hoping to see?
Hi Jason, v2 of Namevine is in the works and will include this feature along with a significant revamp of the system (core functionality will remain).
Hi Andrew, thanks for the feedback.
There is a "restricted list" of words for .CO domains that we'll incorporate into our results, that will correctly mark web.co as unavailable among others.
As for facebook account registration, there is no one-click way of acquiring a facebook vanity URL. I'm planning on adding a popup with instructions instead that will be clearer in helping you get the FB vanity URL you're interested in.
