Regarding Subscription

I would like to know if i purchase a premium subscription will i get perks of platinum as well. As premium is 25 // and platinum is 15.

I wanted to make sure, because i want content which is a mix on both subscriptions.

Yes Premium is the maximum membership to get and due all is taking like a donation due all benefeits you get. The basic is Platinum but if you will get all with Premium you can get it all contents. That includes Platinum and Premium aswell.

Many users have acquired Platinum and as for exchanges to Premium members but what is the purpose ? Premium gets it all so i think it's unnecessary.

I have many users who ask me that due once you get one you can't get the other one, so i make the upgrades manually with the extra fee so the recomended is to get the extra 10 to obtain all forum benefeits
