Pfffft-
That's a lot
I'ma suggest something that helped me when I got overwhelmed with rps on a different site a while ago
I picked a few rps that I really really liked, like, if they were interesting to me, or they would get interesting, and I would reply whenever I got a response
After those were out of the way, I would go to replying to a different group, probably one I wasn't as into (yet) if they had replied
Then I would move on the the ones that weren't 1 on 1, if three other people had replied, I would
So, the first group would get the first responses as they replied, the next group would get theirs after, and the multi- person rps would get responses after other people had replied
I sorted the group not just by the ones I like but by how often and quick they were with the replies, if someone is replying 2 minutes after you, put it in the first group
But do not focus on one rp in particular, while its ok if the others haven't responded, if multiple rps are getting responses, reply to all of them
Yes yes, this was my ted talk-
no but jokes aside this really helped me when i was overrun with rp responses-
so try it if you think it will help
