We should close this thread now! I don't think that Matt, Steempipe, Ello, Alexander Esslinger, Oliver, Rhuarc, Rigoletto, Ventilator, Drew and so on didn't contributed and helped less in shaders than others did in other subjects as modelling and coding.
I continuesly had a look at the discussions in the shader forum right from its beginning. There already IS a nice collection of shaders. IMO it would be nice to see them placed and updated in the wiki, that would make the things less confusing. And several questions might be repeated less often.
Loco's complaints happened right in the time when Rigoletto built up his first tutorials. Which are great start, that should be supported with sequels, additions and hints - in the wiki!
