The problem is what providers can expect from sponsor forums like these.

Agreed with this, but I don't think sponsors are banking on members of the Forum signing up for paid VPSs.  I'd have thought their intention would be more along the lines of marketing their business and making people aware of the quality of their products.  Think you mentioned this too - like the way you put it - brand presence.

I like your idea about social media.  Maybe if one can get the membership to get extra credit if they click on "like" of our sponsors - or thank them for their great product - provided it is great of course - do you think that may be an idea?
