Meh, I don't know...See...I've spend countless of hours looking for an answer to HH, but if I were to actually find one, I'd just share it for free...That's what this forum is or should be about.
If it would be a truly brilliant idea I would like the acknowledgement, sure, we're all human...but I find it a bit tasteless to ask for monetary compensation when you would really know something that could improve the lives of many people.
You're free to do what you want of course (well, till a certain point) and selling an ionto schedule for 10 bucks might count under harmless, but I would at least start by omitting things like 'guarantee it will work' cause frankly, you can't guarantee that...just sayin'
