Dear Graeme, first I'd like to thank you for your invaluable contributions in different places, last not least for offering so many great tools in Argyllcms! Because I'm knew to your list I'd like to ask a question which seems not to be discussed before. Often questions regarding Argyll will be related to other questions about colormanagement, color appearance, color measurement or color knowledge in general. I myself have a question about gamuts, which I have not posted here, because it's off topic and not direct related to Argyll. How do you think about side-topic or off-topic discussions on the argyllcms list? I guess so far the OT discussions have not been too much. Otherwise you would have splitted the list to a developer and user list? In other words: Do you tolerate or maybe even encourage to continue OT discussions which evolve from an Argyll related posting? Otherwise the color newsgroup sci.eng.color might be the best place to continue? Best regards Peter
