Added 'Share' Social Networking Tab

[Babyfacemagee]

I added a 'Share' tab with common social networking icons on the left of the forum.  If you scroll over 'share' the tab should pop out and give you the option of several leading social networking platforms to share pages and topics with.   I'd like to get some feedback as to whether this is useful or not.  We do have a social networking 'bar' under each post but I feel they seem to kinda get lost down there.   Is this 'share' tab too intrusive or is it useful.   It does provide Digg and StumbleUpon as well as Facebook, Google+ and Twitter which already are on the page.   All feedback is welcomed.
