That would be a good idea. I usually try searching first before posting a question, but it usually goes like this:
Search: Drybrush
Results: "...I used blah blah to drybrush this piece..."
"...I finished this off with a drybrush..."
etc.
Never have any luck finding what I am looking for, such as, "what is drybrushing?" So the question gets asked. Again.
