Your of course welcome to pay for Inferno, but might I remind you this is and will always be a free hack.
Now I cant prance into a board running Inferno, look at their features and code them into this. But I CAN take suggestions for features from the users.
I dont know Infernos features so if someone were to request that feature x and y were added, I wouldnt know if they exist in Inferno or not.....
