Wiki Wiki

I'm getting tired now. I looked through wiki and I found out about it. Like it saids it's easy and quick to create. The only problem I have is about going in and editing function where you can add as you please and delete. I don't know if the information is true. But I can see where Library can use to to post about their library events. I learned in one crash course I took that wiki is not the best source (wikipedia). So I am in doubt in using in wiki. I don't know how to post in wiki sandbox. Maybe I'll try another day. If someone can help it will be nice.
