Under the finder there is sometimes a folder/sections called "Shared". When I click on it the only file in there says "Canon Folder" which I'm assuming is a picture folder, but I can't do anything with it. When I get info on the main folder it says it's a PC. None of my roommates has a PC with the name that this one shows up as. Does this mean someone is periodically using my network? If so how do I stop them/kick them off? We have a password already. EDIT Also, there is an option for me to "Connect As". Guys, I have no idea what anything means on anything haha.
