Anyone can revert vandalism and bad-faith edits, but it takes a couple of clicks in the page history to get it done. Users with the "rollback" permission are able to undo bad edits with one click, by using the rollback link on diff pages, user contributions list, or the list of recent changes.
It is important to note that admins (including bureaucrats) already have rollback rights by default. The right can be optional for a user to have rollback and admin combined, but it will not add extra speed even with slower internet connections. Users with rollback rights are just users who are not necessarily an admin.
Rollbackers (users with Rollback rights) can be seen via Special:ListUsers, but they do not by default have any special title that appears on their user page.
I haven't been contributing much to this wiki lately due to me being on family vacation in August 2014. It's hard for me to edit this wiki when I'm visiting places and seeing family members. Plus, not all places I go to have good internet wifi. However, I am able to contribute to this wiki late at night in the hotel room.
First of all, go here: http://spongebob.wikia.com/wiki/User_blog:Jensonk and then press Create blog post and then type a topic in the bar below the Blog post title and then add anything what you want there and then press Publish and then you are done.
Hey. I notice how you edit the same page up to 5 times in a row. When it comes to sections, it's easier to press the Edit button at the top and edit it all at once. Just letting you know since you've been doing it quite a lot now.
