As far as I have seen, over a number of years, Dennis Gentry is probably the best. I think debate over methods and reporting requirements and downright arguements sent Den back to his old day job....although I have not spoken with him lately nor do I know whether he has posted here lately.

Of course there are self proclaimed experts such as ***Unnamed, GMS, Sollog, Dr Turi and others...but most are or have a bent towards quasi-religion. When I started this for myself back in the early nighties...I did it for fun...The very first post I made was met by sceptics...and it has been that way since...so considering that I am trying to have fun:-) I have chosen not to post either....
