The exact statement I made was:
With the major emphasis being on thanking people who are already contributors.
My original reason for setting it up was for when I would decide to have some sort of special sale and use that forum to notify contributor members here FIRST about it. That would give them a head start before anyone else caught wind of it. As for stimulating people to sign up for a contributors member, well, I maybe, but I haven't heard of anyone who was overly influenced by that particular perk.
But that being said, I think all it would take is to catch ONE special sale that you would take advantage of to pay for the contributor membership several times over. I guess it's up to you whether you think this is worth the risk of maybe wasting $25 here.............
