A Error+Need of Protection 

Hello, I want to report an error on Wikipedia: Perhaps it's just on my Computer, but sometimes when I put my mouse pointer on the area where there is the username of the user and link to it and the talk page link and all, it weirdely shifts to the left! And the other thing is I say the Wikipedia Intro page definetely needs Protection so only admins can edit as lot's of people vanderlise it and put ad's or usless info and such on it, and it's very effectful if it's an ad becuase almost every new user goes there. So please look into these two matters. Thank You!
