Fair enough it is a bit technical, probably a bit too much. Have you tried the hire a freelancer section, lots of experts on there who could custom make a pluginIt seems a bit technical for me. That's why i'm looking for a plugin.
I've looked at the free version of pretty links that seems to offer 301 and 307 redirects but i'm not sure if that will blank the referer.
Do you need to blank the referrer or cloak?
