You will notice that, as of right now, many of these are created by LiquidDota staff. This was largely done to allow us to populate the forum for our launch last week, and give people an idea of what a simple OP can look like. If you're interested in creating a new one for a player that does not yet have one, feel free! If you're interested in maintaining an OP for an existing one that is out of date, feel free to send me a message and we can arrange that too - although it's far from required as the important discussion happens later in the pages and will not always focus around the first post.
For some, like EternaLEnVy, the player himself often frequents the thread to interact with fans. It's fun for the whole gang, as they say.
Enjoy! Happy posting and all that.
