As I am still involved with it, here is my periodic post about Drum Corps Wiki.
To those unfamiliar with it, the DrumCorpsWiki is an on-line encyclopedia of drum corps all over the world, past and present. Have a look and contribute what you know about corps you have marched in, seen, supported. It doesn't cost anything and it's fun. You may have already noticed it coming up in web searches for your favourite corps.
I have been entering things about Canadian drum corps whenever I have a minute. Help me out!
