I am so busy at the moment , which is a good thing however the last challenge became quite heavy and slowly burned itself out. Dave spent a long time preparing thee last one, using his own free time to get it together. Once bitten twice shy, as for the number of forum leaders it is a bit low, however my thoughts are that they should be open and have a proven track record in the industry and not be personality driven.
I like this forum and remember that matte painting is a niche field. The majority of working matte painters spend more time cleaning plates than creating space operas and tolkienesque vistas.
Some guys are just too busy too contribute. Many do not like to take there work home with them.
Also some artists are contractually tied against speaking about there work. I have recently got a Non disclosure contract which means I cannot speak about photography related matters without clearing it through my clients.
However hold on as the next twelve months are going to be pretty special for matte painters as various long job films are coming out which are going to blow your socks off, trust me I know 
As for the mentoring side of introducing matte painters into the forum and improving them artistically this is one of the best forums to be on. have patience and hopefully by summer there will be a challenge of sorts to work on. CG society has plenty of challenges with a sub prize for matte paintings, so there is always something for you to take part in. More importantly some of these are team challenges and the more you put into these as a team player the more you learn and create future contacts.
Have patience,
Rich
It will come to you :arteest:
