Quoted from spiroagnew:
Depends on who's asking for the help and who's giving the help, I suppose.
rolf_martin_062 has chimed in on a couple of my EM issues in the past. I've found the schematic snippets he posts, complete with colour-coded notations, really helped me track down issues and expand my EM knowledge. These visuals also help get Rolf's point across, with English not being his first language. Thanks, Rolf!
This. Rolf's posts are awesome. Any issues with language are lessened greatly by the images provided.
