Write a blog post to your blog (or if you don't have blog write a news paper article) about as many as possible international IT related competitions that students (school students, undergraduates, post graduate students and etc) can take part. Examples may be GSOC, GCI, Google Code Jam. For each competition write a brief introduction about it, what happens in the competition, who are eligible to participate, generally when it happens there, who organize it and what a student can gain from the competition.
