Log in with your Yahoo! ID to communicate with your online friends."

My dear and respected teacher


1: "Log in with your Yahoo! ID to communicate with your online friends." correct?
2: "Log in with your Yahoo! ID to check your Yahoo! mail." correct?
3: "I want to sneak into the room." OR "I want to sneak in the room." ?
Thanks in advance!

1: "Log in with your Yahoo! ID to communicate with your friends online."
2: "Log in with your Yahoo! ID to check your Yahoo! mail."
3: "I want to sneak into the room." You are entering the room.
4: "I want to sneak in the room." You are in the room [already] walking like a rat that just stole some cheese. The second rat, of course.

They all sound good to me.

I'd say "Log in to your Yahoo! account"

When you say "Log in with your Yahoo! ID" it sounds like your using this ID for some other purpose than accually access your Yahoo account.

Your ID is your user name. Your account is all the stuff you access.
