I believe that in regards to do's & dont's we can get all of the info we need right here on MR. The problem I always have when sitting with so called experts is that they, like all of us, have their way of doing things. Just look at DSB vs BB etc.
There are plenty of guys (just look at some of the tanks) That are successfull reefkeepers. I think that if any kind of seminar should be held it should be geared towards the newbie. How to keep a reef with minimal money. There will be no discussion as to which way and how to dose and other complex topics.
It should be a session on hoe to properly start. What kind of tank should people buy. How to do basic plumbing so new keepers dont encounter overflows. Compatibility charts so people dont keep acro in a dim impure tank of 20g with 5 tangs.
How often do we see new people that make the same mistakes over and over again.
There are so many experts here on the board. Take Jhale to teach basic carpentry. Deepwater to teach basic plumbing. Jackson to talk on skimmers. There are so many things to teach.
Rather than using the resources to have an expert talking to people who have successful tanks, the resources should be dedicated to creating a section on the site with how tos, videos on carpentry, drilling etc. I believe that that is what the people need. In my opinion that is what MR is lacking - a good how to section.
As for me, I am more than willing to dedicate time and resources to a project like this. I can think of a small team between the people on this board that can make this happen.
Just my 2 cents
