We have a refer system which registers what site the user has come from to Sponsor win. The active sponsers are alocatet to the webmaster this way. Whenever there is a draw for the sponsors, there will also be a reward for the webmaster. The webmaster wo's sponsors have bought most pixels will receive the same prize as the sponsor who has won at the time. Amongst the rest of the webmasters who have sent active sponsors a consolation prize will be raffled off.
You HAVE to do nothing ;-) But, if you support the idea, then write about it on your site or your blog. Wherever you find suitable or possible advertise and place a link for this idea. The referer is the easy option and will be tracked automatically. This will work even if you link from a profile like MySpace or Facebook. The important part is that the user comes directly from your site on to http://sponsorandwin.com/
Sure, there are other things where i could do with help, Anything which aids the cause is welcome. The only thing that springs to mind at the moment is, through the donation of prizes. Would'nt it be great if the prizes would be of high value, this would encourage more user to participate which would then again help all in the end.
