I was wondering why I wasn't getting any replies to my messages on the RWP list, then I realised I had it set not to send me any messages at all. Got it now set to only send me replies to topics I'm subscribed to. The groups.io interface is a bit of a pain in the arse but I think it's worth it to get to know. I was tired of getting deluged in e-mails from lists, and now I can dive in on the website and only get e-mails about threads I care about.
