Has anyone done a Play-By-Post game? Tips?

Has anyone done a play-by-post (PBP) game? Where you play online not in some service like Roll20, but in a forum structure (like Reddit, the Paizo forms, or, hey, here)?

I'm thinking about starting a PBP game of Pokemon: Tabletop Adventures somewhere (maybe Reddit or Discord, not sure), but I'm not sure if I want to create maps for the whole thing. When I was working on my homebrew 5th Edition campaign, the thing that annoyed me most was map creation (mostly overworld, but since this is Pokemon and I know where I'm basing it off of, I don't have much trouble with that). I'd only use "maps" for combat (more like I'd use a combat grid that I steal off of Roll20).

Would anyone here that have either run games in a PBP format or just GM'ed games in general have any tips for doing something like this?
