Events

Greetings from Lordaeron,
I was reading the server's rules and I noticed that casinos are not allowed. I haven't noticed anything about players making events (ex.: 2v2 tournament with a gold reward) so I have a couple of questions. I need detailed information on what is or isn't allowed.
1. What kind of events (made by players, and not only guild events) are allowed and what kind aren't?
2. If I would want to advertise them (ex.: Saturday 8 PM 2v2 event, rewards included, /w me for information), would that be allowed?
3. Would advertising on the forums be allowed? If yes under what section?
Thanks for the support.
Note : This thread will probably be edited with an addition of more questions.

1. Any kind that you like so long as you don't break the rules. Like for example, don't ask people for an "entry price". Anything that could result in a sort of scam, or is considered inappropriate, should be avoided.
2. Yes. So long as you're not asking for donations of some sort.
3. Yes. Same as #2, so long as it's in an appropriate section of the forum. In-game event on one of the realms? Post it in that realm's section. Video or graphic making contest? Put it in the Community Creations section. Etc.
