Hmm well Joe I put some thought into Guard's suggestion as well. A more easier approach would be to make an Inventory Expansion Item that only P2P members can buy and use, then when they no longer pay for the P2P they keep the Inventory room. This would make sure F2P players could not get the inventory space and for the only way to get it would being have to pay for Membership. In a way, even if a player pays the membership fee, you still get some money out of it.
Determination, Pride, and Courage is all it takes to be successful!
