I've received a number of messages from people stating that they thought they were connected to me on Facebook - only for them to find that the person(s) involved were just using my name. I can't imagine why anyone would do that where my name is concerned but apparently they have done. Therefore, I thought it might be best to list the sites I do use and provide the correct links.
My website: http://johnhelvin.net
MySpace (Please note that I seldom use this account these days)
I do have a Google+ profile but do not use it much.
I have been trying out Vizify but have not been impressed as yet; it seems to generate random errors in the data it presents on its pages.
