I'm setting up a knowledgebase using a nice Sharepoint template I've found. So far, it looks like it will fit the bill nicely. However, I have some questions re: the general security of SP itself. In the image below, there are the link bars on the left. In its simplest form, I would like "Visitors" to only SEE the stuff under Knowledge Base, but the Common Actions to not be visible. Right now, just adding them to the "Visitors" group, they are able to see the links, but clicking them gives an access denied. I'd like to just hide them altogether for that security group. Is this possible?
