Try opening up a general support ticket as i don't think account upgrades are done automatically. Even with paid upgrades i noticed this as after i paid for my SuperVIP there was a waiting period. My guess just the time until one of the LNB-Hosting reps approved my order.
I believe you are speaking about the referrals scheme for LNB-Hosting administration dashboard, I have around 15 referrals and they are all pending and even though it's been more than 30 days they didn't change to active or cancelled.
I contacted LNB-Hosting and they said that all the accounts will stay pending until one of my referrals gets at least 10 active clients and accounts.
For the forum post count, I reached the 50 posts today and still haven't been upgraded. I am not even aware how to.
However hopefully I get a free vip upgrade even though I am already looking to buy the Super VIP in the upcoming months.
