CrazeeDonkee might be right... If you go that route, I would use something more masked, like 'n0_sp4m'
However, I wouldn't use the nospam thing for a school page, I really don't think you want to confuse people about something like an email address...
Forms sound like a good idea, but don't you have to include the email address destination in the source code, At least, I think that's what you need to do for FormMail....
Another idea is that you can make a small image that has your email address on it, that way there will be no source...
Or, better yet, how bout this?
Why don't you
encrypt the source code of your page with this cool javascript thing I got from cyberarmy.com, check this out, it may be what you're looking for:
