Can't see why folks can't be part of Facebook and here, think I'm in about 10 gas forums on Facebook, most I never joined I simply had my name added by others and out of the 10 groups there are a couple brilliant and pure knowledgeable ones, the others are simply horrible with some nasty folks on them , so I just like Gas chat which is brilliant , they've been going round the country fitting an install a month dedicating it to charity , candlelighters, really good forum and another is echotechnician , learn loads and in depth , but I still prefer this forum as facebooks are private and you can't get questions from the public just other engineers which is also rewarding , I suppose it's there loss if they leave this forum as many were here for years ,
