I agree with Reuven, two separate forums would work better. I'm a graphic designer who, by neccessity, learned a bunch of TCL commands. I think the OpenACS project as a whole would greatly benefit from the input of graphic designers and other non-techie types. The "tech types" are the ones who make it work, but it's generally the graphic designer types who add the sizzle that sells the steak.
I'm not just talking about pretty pictures, but also addressing the glaring usability issues that crop up with OpenACS on an everyday basis. Allowing graphic designers to get together and speak with OUR jargon can only help the project as a whole.
