: sharing a computer
Welcome to SA dogmuppet :smt006
Until I got my laptop (my FAVORITE win!!!) 3 of us entered on one PC. As manswife says, make sure to log out/clear cookies between sweeping sessions.
I am the major sweeper of us 3, so I check the rules for entry limits - and even though some sweeps allow you to keep entering for the GP after hitting an IW prize, when any of us hit on the 1 prize per HH sweeps, I make sure we ALL drop that sweeps!!!
As far as WHEN you enter? Just amke sure you pay attention to time zones - if a sweeps is on PST or CST and you are on EST you should be OK, but for me (on PST) I have to watch my times.
