Hi Curtis,
thank you for the answer.
What I am asking is an add-on for membership plans. Let me give you an example.
Lets say I have 3 membership, free, bronze and gold.
Now lets say that there is a new listing added on monday. Only gold members can view the contact information for 2 days, Wednesday.
On Wednesday, god and Bronze member can view the contact information for 3 extra days, so until Saturday.
Only on Saturday, if the listing is still there, that free membership get to view the contact information for the listing.

Hope my example was a more clear!

It gives an incentive for free members to become bronze or gold , because if there is a listing with a good deal, they don't want to miss out on it.
