OFA registration

I find it a really challenging to understand and figure out how and what I need to do in order to make all the testwork on the dogs official. So I DNA tested the dogs through Wisdom Panel for a lot of deseases (more then 300). But the most important once (Mdr+ and DM, all 3 clear) I also need to register  (and authenticated) with the OFA. Tomorrow I will send in all the forms with testresults. Hopefully this goes smooth. Then the only thing to do is hip and elbow testing. Still not sure if OFA for the hip, or PenHip.
