Been looking for ways to upgrade. I'm a member of one website (and know of another site) that you can upgrade by purchasing (from my local store) a voucher, which allows me to upgrade using the code on voucher(much like topping up a mobile phone). I use my mobile phone, to upgrade aswell. I just text my account name, and in an instance, I'm get upgraded.
I'm not upgrading because of the recent abuse by trolls on Chess.com
Mods can make what you will of this!
