New Post: against limits

Hi,

I am currently optimizing my project and currently realized that I am calling getting User object more than needed. But I am wondering that if there any differences between these two codes "ILoggedUser.FollowUser()" or "User.GetLoggedUser().FollowUser()".

Also I tried both FollowUser(userid) and FollowerUser(User) functions. I think the first should be used not to call User object. Is there any easy way to to do follow a user by just entering the screenname?
