I do however try to include "10ER" in the subject heading if I start a thread that is 10ER specific so that members who are not interested can skip that discussion.
On the other hand unless I win the lottery, (and I don't buy tickets, so that isn't likely) I will never own a PowerPro or a 510/520, but I still read posts that cover them, there might be information there that is also applicable the equipment that I do own, and even if not it is interesting and instructive to see how problems are diagnosed and solved.
