As you see under your profile it states ” Your not a Paid Member”. This is only temporary and will be resolved later this week when subscriptions services are activated. Dont be concerned as your account is already set as a paid member.
Currently you can show them your post with "paid member" under your Avatar. We are working on adding membership cards directly to each members private profile (you will be able to print your card there). It will include User Name, Real Name and your membership expiration date. It will probably take about a week to get that in place. Sorry about the delay in getting this completed.
