As others have said, there's a lot of different visions of "post-apocolyptic". For most scenarios though, having good politics and a focus on mutual aid is an extremely important factor in the safety of a community. As Anarchists we aim for creating safe spaces from those that would attempt to dominate, exploit, or destroy us. I have confidence that as the society around us corrodes, the Anarchists will have the safest aim. This is a long way of saying that almost any role of someone in a community is useful, even the disabled. It's about the community for survival. We are social creatures.

What I would bring to the table includes patient and thorough scavenging, general homesteading skills, trapping, butchering, canning, etc. Also, art, poetry, writing, and game design.
