Many of us Forum Folks have gotten to know each other over the years; and we participate in back channel communications -- nothing nefarious, just a bit of coordination of answers, and gentle reminders there might be a better way to do/explain something. This tends to help keep the Tableau forums both informative and non-combative; traits I'm sure we all appreciate.
I mention this because the primary contributors to the forums have recently gone through a major turn-over. There are many folks posting quality answers that aren't currently part of the back-channel email list. If you want to be included send me an email (my address is on my profile page). Thanks,
