Re-registering at Trapperman will be worth the effort. Paul Dobbins (the site creator / owner) is just looking out for the site's best interest with his semi-strict application process. His late father Charles is a trapping legend (Paul is no slouch either), anything written by the 2 of them is worth reading.
If you want to get into k9 trapping at all, I have a personal recommendation on a very good video to get. Here's the link. Darin is my uncle. The guy is a fanatical madman when it comes to trapping. He catches 4 times the coyotes than anyone I know and in an area where we have quite a few but not hordes of them. The video is very well done, IMO.
