I've been sport climbing for a couple of years and am just now getting into trad/multipitch.
A couple of friends of mine are thinking about doing Condorphamine Addiction at Leavenworth sometime next month. The info I've seen online suggests a double-rope rappel back down the route from the top. Since they will probably be doing it on a weekend, I would imagine that there might be some folks climbing it below them. It got me wondering: if you have to rap off a route and there are folks below you, what is the proper "etiquette"? Do you wait for the climbers to get to a belay ledge before tossing the rope down, or do you just yell down that it's coming and let them fend for themselves?
Also, I was recently out to We Did Rock at Exit 38 for the first time. From the condition of the chains, it looks like a lot of folks are toproping from them. I ran my rope through a different link to rappel once or twice because the bottom link looked so worn. If I see someone doing this, is it acceptable for me to politely point out that it isn't good for the chains, or do I just suck it up and continue to rap off a different link?
