A
wiki is a collection of web pages controlled by a certain software to allow easy editing of the content and collaborative work on it.
Wikipedia is an example for a wiki (the most famous one). Our wiki.animesuki is another wiki. Wikipedia's rules do not apply to wiki.animesuki.
As for further content, my stance on any "You should ..." is "NO." My opinion on any "I'd like to do ..." is "Go for it."
At least as long GHDpro gives his blessing. Just don't overload the upcoming anime pages itself with information, or worse, placeholders for information no-one enters.
