[ANN] Spelos' Development Challenge

[Spelos]

@Daniel47 I haven't thought about that... Anniversary was a challenge of its own but I'll try to come up with something else.

The format of "Challenges" doesn't appeal to me as much. I'll most likely create some new Code Snippet that would be fun and easy to implement and release it as a resource. Anyone can then use the snippet and share their work if they want to.
