Yeah I read everything! Ideally as they come out, usually within a few hours. In my RPs we all make sure to post a link or a notice when we put something up so everyone knows! Except Karen never does it for Trainers >:( But because we do that I think it helps some of us keep up on reading and remembering to check the threads! Having a kind of, culture of commentary around posts also is nice. I like talking about everyone's posts!
I'm a little more lax on reading stuff I'm not part of- I tend to let it go for a matter of days or weeks depending on how busy I am. I still need to read most recent Spear post, sorry GP & Fox (・–・;)ゞ It's open on my phone still bc I haven't yet. But I read most things that come thru RP Stage :) idk I like to see it all! It's harder to just randomly send commentary to people about they posts tho when you don't really share space with them.
