Landmark has an online introduction now at
Landmark Education: Seminars, Courses & Landmark Forum, so you don't have to go to an in-person intro and risk the vigorous persuasion that sometimes goes on at those things! I hate to be pressured; I'd much rather do my research online and make my choice on my own, so I like this online intro thing.
If your friend (or anyone!) has any questions or concerns about the Forum, I'd be glad to talk about them from a user standpoint. I am not a salesperson or affiliate or anything like that; they don't give me a toaster for talking it up. I just feel it's a really valuable tool for creating a life you love.
