Everything that you contribute to this wiki is licensed to everyone else under CC BY-SA 4.0. I figured you should know.

The stuff that Rob Lanphier (User:RobLa) contributes? Well, you may have to ask him. He might have copied it over from electowiki which has a different license. He might have copied it from Wikipedia. You might just want to ask him, and assume that his content is this:

But generally, for stuff that he writes, User:RobLa is usually cool with CC BY-SA 4.0. One of these days he might actually read it....
