Back in July I started a RT and Follow competion to give away some tea at 500 followers. It took some time but we got there.
The winner is selected from amongst the followers using the following process.
The followers list was exported to a spreadsheet, with each follower being allocated a position number based on when they followed, ie the first follower will be position number 1.
A random number generator was used to select a follower between 1 and 560.( Followers at the time of the draw).
