Probably about 20. I am not sure unless I open up my domain name providers and count them. I am currently implementing a new domain name strategy. Previously, I bought domain names with both .com and .co.uk suffixes. I am now letting most (not all) of my .co.uk domain names go and will be buying only .com domain names from now on. The reason for this is privacy protection. The registrar for .co.uk domain names only allows privacy protection for non-trading individuals, whereas you can get privacy for any .com names, whether you are non-trading or not.
