One idea is when the incoming freshman come to your high school for a demonstration or orientation, show off your robot and have a sign up sheet on a table so they can write down their name and email address. Also, pictures of past years/build season work too. On Thursday my high school had an open house type thing for this program I'm in and our team brought our demo bot with us and 3 of us showed it off and talked about our team. We also had my laptop there with a slide show of pictures from last year and this year, both competition season and build season. There weren't many people at the open house, but we did manage to get 2 8th graders to sign up and our team leader is going to email them in a few days.
We also brought our 2008 robot with us to my high school's Back to School night and got at least 2 new members from that.
