It's currently the British definition of summer: a few short weeks in which to fit all the swimming, surfing, skating, cycling and sightseeing you possibly can. And, to prove you actually took advantage of the sun instead of sitting in a darkened room complaining it's too hot, we're giving away a GoPro Hero3+ Black Edition for you to catalog it all. This top of the range GoPro comes with a wireless remote, waterproof housing and selection of mounts to get you started, and was provided by the team at Tagstr.

Accessible on the web or through its iOS app, Tagstr is a media-centric social network that groups uploaded photos, videos and audio based on their hashtags, creating "shared moments" from the content of its users. You have a personal profile (Facebook and Twitter login is supported) which friends can follow, but the real point of Tagstr is to explore and contribute to "moments" for different events, themes and more -- the perfect place to share some of your #summer GoPro footage, perhaps? In pursuit of a free GoPro, anyone can submit up to three entries via the Rafflecopter widget below. Oh, and give the rules a quick once-over while you're down there.

Winning: congrats to Dave S. from Belfast!
