Hey, I would like to submit a plugin, how do I do it?
It's a modification of rfc1920's MyMiniCopter plugin in which I added the ability to spawn Scrap Transport Helicopters, am I allowed to submit it?

Sorry, we do not allow forks of plugins like that. The code would need to be your original work, as stated in the submission guidelines.

Have you asked @rfc1920 if he would like to implement that feature ?

It has been asked repeatedly.  I don't currently have time to implement it.
