As far as I can tell, there's nothing there that really links Tecshare to Woodcollector other than the video and directory. It is very curious, but I haven't seen anything that would show WC is an alt of TECSHARE.
It's confirmed by BadBear (Who has access to IP addresses) that TECSHARE is not an alt of WC, as he hasn't marked TECSHARE with neg trust, with it reading "Alt of WC" like he has with alts.
