To my own personal experience of other games, being a watcher/moderator requires numerous traits and functionalities.
To be a mod, you need to be vigilante, responsible and experienced, however, so if you want to be one, make sure you have the attainted characteristics.
Before you decide on if you wanna go for the moderator position. Consider how you are as a person. Would you have to change to be one? Wouldn't that be a waste of who you really are. Being a mod isn't the be all and end all, it's a job, a duty, a responsibility. You get a bombardment of messages, only a few being an honest accusation related to your duty, some being spam, and others hate. Once the game grows you will have even more of a responsibility. All in a days work, though, right.
You also need to have a good knowledge of how to handle problems, meaning you have to be quite intelligent in dealing correct punishments (knowing your rules inside out) and helping others with their issues, you gotta be skeptical and show discernment.
Being a mod would be good for some and bad for others, dependent upon your personality, just my two cents, though. It's a hefty task to have upon ones shoulders, and isn't for the people who can't handle being critiqued and under heavy observation for every action you take, everything you do and all the things you say. Because being a mod in other games, from past experience, results in that.
Being a mod, on a forum, requires you to prevent spam, attain high morale and keep a steady pace of balanced and respectful diversity in the said community, in the case, ours!
I, personally would love to be a watcher, seems like my kind of thing. I speak fluent English and can converse with community members and other colleagues easily. I am mature enough to handle any obstacle thrown at me and I am a very experienced forumer. I am pretty intelligent and have the problem solving skills to be able to overcome issues and I am pretty good at the game, which helps.
Thanks for reading.
