https://electronics.stackexchange.com/questions/182864/arduino-relay-shield was migrated to the Arduino Beta stack. Aside from it having NOTHING to do with Arduinos from the meat of the question (will this new design work?), it seems it was blindly migrated. Was this a request by OP or what?
As no response is forthcoming, it's obvious that one Mod has decided that Arduino questions are off topic, despite established community policy that they are on topic, and that questions are not supposed to be migrated to beta stacks against standard Stack Exchange policy as well. He will typically snipe any question he feels is ""off-topic"" to be migrated out within minutes of it being posted. This is unacceptable. Moderators are not supposed to dictate policy, or ignore the community, they are supposed to enforce what the community decided on.
