You referring to that little World icon on your Facebook wall or "FARMVILLE REQUESTS which appears in the upper right of your Farmville playing area?
The world icon requests all have time stamps associated with them AND they are simply notifications. Typically, when they get really annoying, I just click on the World and mark them all as read.
If its the FARMVILLE REQUESTS, I have answers other than go into the "Games" area of your Facebook page, then click on "REQUESTS", then click Ignore All". I usually end up with over 1,000 "old" requests which I go in and "ignore".
As for rotating the buildings? Some buildings you can rotate while others you cannot. Basically, if you click the building and "Rotate" does not show in the popup menu, then you cannot rotate the building.
