Please get in touch first by sending me a private message so I can check it out and approve it. While it's awesome that you're starting an event, we have to be careful to give things a once over first. Note that this isn't approval you need to do an event (anyone can do an event), just to post it on the boards. If you post about it before having it approved, we will not allow you to promote it here at all.
Note to users: if someone posts a thread and you don't know if it was approved, just report it and don't post in it. If I see you going into threads to be shitty to people who are trying to raise money for a children's charity I will sit on your head.
