Per Gaius Baltar’s great suggestion, The Legend Of Random will be hosting regular crackme challenges. I don’t know exactly how often yet (it depends on if other people contribute or it’s just me). It would be nice to have them every week at a set time, so everyone can try their hand at it, but we’ll see. They will range from easy to extremely difficult. They will also (hopefully) be in several different programming languages, using various techniques to thwart the would-be cracker.
I have also added a “Challenges” section on the site (see top of screen next to ‘forum’) with an area to download the challenges and a status showing who cracked it first. In addition, there will be a small description of the challenge and a place to download it.
As most of you know, the prize giveaways on this sight are nothing short of spectacular, and I’m hoping to have an awesome prize for each winner* 
In order to get in the spirit, I have uploaded the first crackme. It is a simple one, but you MUST supply the correct serial. No patching, but keygens are allowed (though overkill). The first person to post a solution in the “Challenges” forum will get their name on the scoreboard. (Members of the Super Secret Elite Cracking Squad- sorry, you don’t get to participate 
.)
If anyone else would like to submit a challenge (please), for now simply email them to me. Hopefully, before too long I can make it more automated. After I or one of the SSECS team members (that sounds disgusting) checks it, we will post yours as a challenge as well. I only ask two things; please do not steal others code (as I’m sure I’ll get in trouble) and please try to make them unpublished, as it’s more of a challenge for people. Other than that, the sky’s the limit. Also please send a description of it (ie. limitations, hints etc) so I can include it in the listing.
I hope this is a great learning experience and you guys have fun.
