This is the Forum Magnum, In Roman times it was the center or Rome from which the rest of the city developed. In TWC the Forum Magnum is a place where you members can start your own projects which help both you and the forum. All you need to do is gather a few friends and Send the Curator of the Curia (Nikos) a Private Message detailing the aims of your project. If, for example, you have a paper to write on Roman History you could assemble a team and have your own small area in the Forum Magnum. The catch is that what you do has to be of use to the forum. So if you write articles on roman history, publish them in the library (Scriptorium) for all of us to enjoy.
Another example would be if you wanted to host a tournament or start a petition about something. The possibilities are endless. The only catch is that if you are a member you need a Civitates to apply for you and be a member on the team, but from that point on the running of the project is totally up to the people who run it.
All this is obviously subject to the administration and the sections will be subject to the forum rules.
