I was not going to make the seeds this year, but did not want to waste them. So I ended up making a bunch (we had 5 pumpkins). Made them the normal way by rinsing, salting generously while wet and then putting them in the oven for 10-15 minutes at around 275. Found this method though to boil them slightly first before roasting to break down the outer shell a bit. May try that next time.
