Any investing tips?

Mark and I are interested in starting to invest money in mutual funds. Not just any mutual funds... green mutual funds. This satisfies me both on moral grounds, and the fact that I think green business has a damn good future. The one I like is Winslow Green Growth.... but it takes about a 2500 dollar initial investment... Money we don't have right now. So, if anyone wants to donate a little cash to our cause, I'll pay you back in 10 years. Or, you can just give us investing tips, 5 people who read this.
