Here are some idea for new Positions.
Event Manager: This person over sees all Tournaments, Events and other stuff and helps the creator of the the event/tournament and in case they dont show up for a long time that person can take it over with an approval of an admin.
Roleplay Manager: This person over sees all Roleplays on this site. This person helps create roleplays with help of other people and can do the same thing as the Creator of the roleplay can do.
Head Tester: This person can test people like other testers but can look at test results and see if they are fair and decide if it is correct and that the tester made good choices.
Others will be posted asap...
