And here we are back at the beginning.
Action Item 1: include access info. If you can get past that one item when organizing and promoting your events, and do it regularly, accurately, with intention? i just may well show up. Otherwise? It ain't happening. Ultimately, it's a numbers game, people: If you want more folks in your community to show up, make it possible for more folks in your community to show up.
Or at least be straight up about who is invited and who isn't. Honesty and intent ain't everything lol, but it can be a start. If i know that your intent is to invite more folks, i'm more likely to work with you on how i think we can make that happen. If, over the course of several claims of "but we intended...!", your event is not increasingly accessible, and there are negligible-to-no attempts to actually address it? Then no, i'm not going to attend and/or promote your event. Please, don't ask this gimp to promote actively nonaccessible events.
But if i see that change is happening, i can totally work with that, add whatever time and resources i may have to help out, and be part of moving forward. But it takes working together on it, and the very first thing you can do is include the access info you now have. One step at a time, folks.
