Bob Sehlinger's vision - how to support long term

I LOVE the Touring Plans, and I’d like to help out more. I first read the Unofficial Guide to Walt Disney World in 1992, and I’ve been a fan of not only the books, but the research methodology ever since. I’d love to be a lifetime member of the Touring Plans organization, or even donate to the cause. Does Touring have a non-profit arm? Is there a way to purchase more than a 3 year membership? Any other ways to support the research? :mouse::european_castle::woman_scientist:
