That tutorial looks like its going to be an excellent peice of work once it is finished.
If you like I will happily proof read it for you, It may not seem so on here because Im very lazy on forums and msn, but I can have very good english when I want to, so let me know. I can also point out some things which bugged me when I was new to programming plugins - I like to think I have the basics well and truely covered by now
