I find it pretty disappointing that people don't take up the free advertising offers. It doesn't surprise me that MW Software do well. Martin is a good communicator providing a great change long on the MW Software website, attending shows and advertising and taking the time to send news worthy material to magazines. Perhaps some others could few tips from Martin on how to make a living out of RISC OS (or atleast some spare change)
I'm sure out in the RISC OS community we have a few good designers who could advise on how to improve advertising layouts etc. I'm not, but for starters...kiddy fonts don't make people think you are professional, think about the colours you use, include your contact details and say something to encourage people to hand over cold hard cash to you (after all you worked hard to develop the product in the first place and deserve a reward). People won't buy something if they don't know it exisits!
Short list of people who could be interviewed for Qercus if is hasn't happened already - Martin (MW Software), Chris (Drobe - I'm sure he is an interesting guy), Andrew (Rcomp), Peter Naulls (what makes this guy tick) and last but certainly not least Druck.
