I have been using aworka since the early days and its an excellent program, at the beginning it was quite basic and it had some flaws, but chris is moving it forward, all you need to do is email chris a idea or a problm with the programme and he will either fix it or put it on his list to update the programe.
What happens if the aworka company goes out of business, I'm not too sure but I do keep a copy of all my work on george as well as printing off hard copies every couple of months, so if both george and aworka go down at the same time I will still survive
