We accept payments via PayPal, Stripe and bitcoin.
We recommend that you pay using PayPal, as this will set up a subscription which will keep your membership valid constantly and prevent any marketplace threads from closing. If you use Stripe or bitcoin, you will have to wait for your membership to run out each year, before you can pay again. This will close your marketplace threads for the duration of time that you are not upgraded.
If you want to pay via bitcoin, please PM Diamond Damien.
