£100 Amazon vouchers, plus runners up mugs.
You could win £100 Amazon vouchers by entering a competition on PCReview.co.uk Forums - you need to make at least 20 posts on their forum (including 1 new thread) to get your name entered in to the draw.
It's a friendly place to post and there is some good advice on tech related topics. The top 5 posters get a runners up mug :).
Members who make more than 20 posts during October 2016, including at least one new topic, will automatically be entered into the competition. The competition will run from 00:00 GMT on 1st October 2016 to 23:59 GMT on 31st October 2016. On 1st November 2016 a winner will be selected at random from all the entries, and announced on the forum.
