Quote from jackophant@Michael Greenwood maybe I misunderstood what you were after then. There's a section there regarding layout, specifically Ben's Bible on Multiplayer Level Design that I thought would help.
You don't have to be present for the playtest, but it is helpful and appreciated. When you can hear what people are saying, you can hear how they say it, text can only convey so much meaning. We use a feedback plugin that captures everything typed, as well as a demo (which you can use on some websites to create a heat map) and make the files publicly accessible. A separate file is stored from text specifically prefaced with "!fb" or "!feedback" so you can get right down to what you can see people have said without sifting through the entire chat log.
Ok, I hadn't seen that. I'll read this through! Thanks for the help
