i know i saw him and i feel pretty much the same way; he doesn't explain anything at all, and just kind of makes it hard to adapt; i find wuppys tutorials much better, and even though he teaches through a specific example he explains what he's doing well enough to be able to adapt if you know enough about programming; in fact the reason i made this topic was because he still hadn't made his tutorial on containers.
EDIT: what should go in getDescriptionPacket and onDataPacket
