FAQ
Q: Nothing seems to happen when I use your plugin or I get an error.
A: Make sure the plugin has its original name and that you haven't accidentally renamed it.

Q: I double checked the name and I still have an error.
A: Please be really specfic about what you did when the error occurred, hit F8 and it'll give you some more details that might be useful to me. Does it happen in a blank project?
