It's just so "Royston Vasey" that most of the contributors to this thread focus on criticising Mr Naulls because he disapproves of random hacks and workarounds to keep the free stuff flowing to the fickle punters. Sure, if it were me, I'd welcome even misguided attempts to remedy faults in any software or documentation I'd released, although I'd want people to publish genuinely useful and factual information. That said, if I were making RISC OS software available only to see other people's contributions top out at rituals and lucky charms from a community who largely doesn't aspire to be anything more than a bunch of tinkerers, even though they may pretend to be so much more, I think I'd blow my lid at some point, too.
As for the financial aspect, I guess it's another lesson for all those people who throw money in every direction and complain afterwards. If you suspect you're not getting value for money then you know who to talk to. I imagine, however, that most of the complainants haven't stumped up any cash at all and just want to use the financial element to vaguely suggest wrongdoing. I suggest that those people either properly make their case or keep their dubious accusations to themselves.
