To all, Thanks for the excellent and thoughtful comments, especially the wise counsel from the 'elders' - there wasn't a bad one amongst them.
Unfortunately I mailed replies privately by mistake. For the forums benefit - a short recap. I agree that it is part of Tomasz's successful (in the past) chosen business plan/vision and also part of his personal style. The help manual is lagging behind the program and the AFL reference doesn't do justice. Tomasz's teaching style is very unusual and doesn't suit all - it is a kind of cryptic language all of of its own - perhaps considered perhaps not. It doesn't have to be a book (that is my bias) electronic is easier to disseminate and maintain. Herman - you are a unique individual - most of the rest of us are not ready for you but that doesn't make you wrong (I'll try to keep up with you). I'm very grateful for what Howard is doing for us - perhaps he will save the day in the end. If I knew half as much as Tomasz about AB and programming I would love to write an AB/AFL book. Graham is a natural teacher but I dont think he wants the job (formally). Tomasz is free to do what he wants (as we all are). Anyone who takes on a leadership role in any field (sport, family, business) soon finds that their responsibilities grow exponentially especially with regard to the least amongst them. The UKB has made a good start - I can't personally do justice to AFL - the site does depend on a variety of authors to provide balance - imagine what it would look like if every long term AB user posted one article on their favorite AB/trading subject? Tomasz has actually provided us with 4 maintained user databases (AFL library, AB forum, third party site and the UKB). The UKB is the only fully structured user site. Our lives are not our own - we all have duties that we try to complete so that we can get some time to ourselves. We all have to quietly balance personal with our public lives. We all have to priortize - I am just wondering if AB has overbalanced and put development to far ahead of delivery. The kids are our future but the future is here now. Have a look at their sites and you will see how they prefer to exchange information. I WON'T COMMENT ANY FURTHER. THE TOPIC HAS BEEN VERY WELL CANVASSED.
