Thanks for all the input so far.
Addressing TchnclFl's point:
This is about circuit diagrams so the logical area is Hardware.
These are the Hardware sub-areas on the forum ...
News - N/A
FAQ - N/A
Workshops - N/A
Bar Sport -N/A
Uno Punto Zero - N/A
Exhibition - This is the only place in Hardware. Looking ahead, once there's lots of schematics, how would I filter to just find schematics? Also, the Exhibition section is for showing off finished projects but a schematics area is partly about browsing through WIPs for knowledge, inspiration and entertainment, partly about offering alternatives to the original poster for improvement and partly about helping to create something quite new.
For me then, a thread wouldn't work even if there was an appropriate area to host it in (which I don't think there is). I appreciate that starting a thread would at least be a beginning, but I don't think it would work.
Addressing everyone reading this:
Come on! You must see the possibilities. I have floated the idea, is there any support as well as critical comment please? Speak up for this idea if you like it or it won't happen.
