Okay, so I was about to do this, but I think I'm probably going to run into issues I want to start a conversation with one of my groups. This group has over 10,000 users... The conversation will contain a step-by-step "click" guide (once complete, they get another conversation for the next step) This site is an existing site that I've recently converted to XF. I need to contact them via conversation and let them know about the updates and I need to converse with them as a group. Is it possible, or is there a hard participants user limit with conversations? Will all 10,000 users be listed down the side of the conversation (this would take a while to load) Am I going to run in to other issue with this many users in one conversation? Will the emails that get sent out (related to conversations) all get sent out at once (if so, I might run into spam detection issues)? Would I be better off doing this as a private thread, and somehow assigning "watched" to all users of that group?
