Short version

As pmdev you have access to code search and all documentations and wikis. ¹

You can also install an old everything and play around.

Long version

I've provided you with many links yet to inform yourself and help developing.

While you haven't provided a single patch yet, you are very vocal in criticizing and demanding change here.

I somehow doubt you'll ever "take the bait" and start with (non-vocal) contributions.
