No, you already have a lifetime account so your status will change from Unlimited to Lifetime.
Something may (or may not, read on) be a little off in how the upgrade process went through.
I am a Lifetime member. However, with the change, my status now says "Premium" - which is fine, as it remains functionally lifetime and doesn't have an expiration date or anything - but unless I am misunderstanding you, it doesn't line up with the description you gave PWiz.
I will also note that for some reason I got zero points to use in voting for trainers this month. Previously I was getting 75/mo like clockwork, but not this month - maybe whatever it is that looks at an account and automates the designation of points in the database isn't aware of all the possible iterations of memberships.
I was a year-to-year member but upgraded to Lifetime a while back, if that helps at all. Again, trainer functionality and availability are fine, and the "upgrade account" page shows me as having a Lifetime account, it's just the status itself on general pages that says Premium (and nothing else); and, I am not getting upgrade points. I guess just a bug or two to work out with the system there. Best of luck, I'm sure it will be fixed soon.
Why im premium if before im unlimited?? It supposed to be lifetime no?? Humm not clear...
I was concerned about this as well but after reading a previous post it appears an unneeded concern because the response from PWiz was basically translated, as I understand it, that if your membership is already a lifetime membership it will still be a lifetime membership no matter what it is called now.
I personally don't think "Premium" sounds so bad.. I am happy as long as my lifetime membership is still sound and secure since I am one trainer usin gamer!
