I would absolutely agree with Steve. Saying that bingos are not 'pinball' is an interesting distinction and there's already the setup you're describing except with a tech section (the flipperless forum). Might as well keep the status quo with that setup.
Bingos are absolutely pinball. Of course, my opinion only, but it's a strong one!
The thought is that you can more easily click into the content you want to see if you are a new pinside user or old timer that wants to see bingo stuff. If you don't, turn it off. Remember, this also makes the site more accessible for bingo folks coming in (new users) that don't like flipper stuff. Yes, they exist. Makes the site friendlier for those folks.
Yeah, it is all EM for the most part, but being able to see all the bingo things would be convenient. I know I love seeing the purely mechanical and early EM stuff in a separate area now for flipperless. Maybe I'm the only one.
Flipperless would remain. Bagatelles and pure mechanical and early EM would still reside there. And arcade machines (sure, why not)?
Levi, bingos are at the York show every year. If you have time, come check them out. I know quite a few people that collect them, but I'm in that world. You have to devote some time and head space to understanding them. I'm not saying that you'll love them or that they're for everyone, but if you want to see some working ones, that's a great place to go.
