hey there, how could i participate in the give away ?
Either post a code in the thread or be one of the quick and lucky few who manage to redeem one when somebody posts it.
Honestly, this thread and its giveaway method (code-dropping) are generally not a good idea, since a majority of the keys end up in the hands of bots. It's usually better to simply open up your own giveaway thread and either hold a raffle or make it first-come, first-served for posts asking for games, but it's up to you. If you still find the code-drop method more favorable, feel free.
This is a much better website for the code-dropping method, in my opinion. Prevents the bot-scumming: http://keygiveaway.com
