Local Secrets

We have about six websites, and you can check, but off the top of my head we have:
www.localsecrets.com, www.local-secrets.co.uk (or com I don't recall), www.localsecrets.co.uk, cambridge-restaurants.co.uk and Cambridge-restaurants.co.uk, www.wavy-hairedreader.co.uk and perphaps a few more. Would it do any good to get some more of these? If so how and what kind?

-- Also sometimes people misspell the name Local Secrets, so it should also be available as local secret, localsecret, localsecrets, etc.

-- Although Local Secrets is centered in Cambridge, it covers a much wider geographical area, and all the towns and regions we cover need to be acounted for. These are the main areas that people might be looking for:
Cambridge, Cambridge City, Cambridge UK, city Cambridge, Cambridge England, Cambridgeshire, South Cambridgeshire, Huntingdon, Ely, Newmarket, Haverhill, Saffron Walden, Royston, St Neots, St Ives
They might also look for: Bury St edmunds, Bedford, East Cambridgeshire, Huntingdonshire.
