Well, this is just my POV... To speed up the development of software - especially something complex and big like a DOS - it's an advantage to write emails and PM's of motivation. IMHO it's bad to comment in an impatient way because this will just lead to increased frustration of the programmer, which - of course - is not helpful at all.
I'm sure that SyX is doing an great and awesome job, but please consider that he is NOT paying his bills from his hobby projects. People doing hardware for the CPC are making at least some bucks with it (except Tot0 who even put's money in to serve the CPC scene), but people making software don't ever get a dime for it.
I don't want to offend somebody, it's just my personal view. You are welcome to disagee (and code something well on the CPC

)
