Yeah, I don't think there is. Everything I know of is issue-specific but I agree that expanding that circle and reaching out beyond the community is so, so important.
My dream for the petition is that people take it offline and go out into their communities and speak about this experience at their churches, schools, universities, community centers, etc, educate others, and bring healthy allies in to sign the petition. That's sort of phase 2
Getting to 50,000 signatures is going to be a process, but I think in many ways the process is more important than the goal (of signatures, not funding!) the process of building capacity, sharing our stories, reaching out to others, organizing online AND offline.
Some of us are mildly affected by this disease and others have healthy people in our lives who love us fiercely and can bear witness on our behalf. My dream is that this petition can be kind if like our Olympic torch - a reason to gather and connect around this huge issue. It will be a months-long campaign.
Ryan and I are also collaborating to connect the grassroots screenings of Forgotten Plague with gathering signatures for the petition - I think the two together will be tremendous.
