/sign

I've been hoping for something like /equipset #, or /macro "Name" for years.

I never buy the "not possible" arguments. I've managed a programming group for 12 years. Techs want to come into my office with long explanations of why something can't work. I smile while I ignore what they're saying. Then I tell them to think more creatively. Most of the time, they come in a week or less later with a working solution, from a different angle. If they don't someone else does.
