I've been asked to re-do my school's webiste, an although I'm doing most of it with Frontpage, I would like to include a fourm. Can anyone tell me what I would need to learn to properly set up and administrate a fourm using the likes of www.simplemachines.org ?

Sage for:
- including a forum on your school's website:
- - no one will use it
- - it will likely include a gazillion security holes
- being an idiot (HOW DO I SETUPPED FORUM?)
- using Frontpage
