I know your site and if I remember right, there were not only the solutions, but a short hint (one or few words) on the basic idea to solve the problem. As I am really unexperienced in algorithms (I never had any lessons, didn't study that kind of thing, never participated in any contest), that simple hint (e.g. not more than "DP") helped me on the one or other problem to look into the right direction.
Perhaps that could be a way of connecting SPOJ and personal website: No solutions, only hints.
