You can sell your ECUMoney to other members. We can send/receive ECUMoney below $10. That $10 minimum is just for exchanges in SwapGold.
Btw, the credits system will still be attached in the forum although most of the members (standard members) won't earn from posting, right? Otherwise, it will be difficult to count our credits. And what will happen to WTH? Will it be closed after the premium memberships expire?
I know we can transfer Ecu to other members but right now no one will be willing to buy Ecu because of its low demand. Now the only way is to exchange my 7 LR for 7 Ecu with other members and then exchange it for LR with swapgold.

About WTH, I even haven't visited the forum, so I don't have any idea what the status is, only think I know is it's not a PTP forum for all members including gold and silver. But I wonder whether the admin is going to refund the membership fees for those members.
