This would be a mistake... There will be no incentive for free members to become a supporting members at that point. You can not expect people to become a paying member instantly. You have to give them time to feel comfortable enough to contribute and you have to make them want to. The way you do that is through respect and catering to their needs just like any other customer. What we need is more members and for them to post information and or questions. Overtime those members will likely become paying members.
If you were selling cars would you tell your customer that you will disclose all the really good information about a car or let him take it for a test drive only if he buys it first. That is absurd
We need to make the core of information available to all and entice prospective paying members with the other stuff like chat and the member's forums... Which brings me to my biggest pet peeve... We really need to start concentrating on the member's forum and filling it up with stuff they can sink their teeth into... I just need some ideas to get it going and I can't do it alone.
I started a thread a while ago asking for ideas but It never got any response.
