Template:Notice signature
Hey, I've noticed you on the Wiki. You're doing great, but I also noticed that on a talk page, you signed your name the manual way (or didn't sign at all). There's a trick to it - type four ~ in a row, with no spaces between them, and you'll get your "signature". Thanks for all your contributions!
This template tells the user nicely to use the signature instead of what they were doing before.
