I think that's a bad suggestion. (In this case, Jason already answered this thread). To the best of my (LIMITED) knowledge, Jason is the guru of this particular topic, BUT Hal or Rob or a dozen other people whose expertise in this topic I failed to observe might give good answers (especially to the non extender parts of the question).

Asking by email has two flaws:
1) You miss out on the chance that someone else who also knows the answer would get to it sooner than the "guru".
2) You're making the guru answer by email, so others who have the same question after you don't get to find it in the message archives.

As the "guru" of some of the other sub topics here, I'd prefer not to get JP1 questions by email unless you're sure that none of the other experts know, AND you're sure no one else will be looking for the same answer.

BTW, I think you should tone down your "ask in the right forum" posts a little. Questions that need a lot of back and forth discussion ought to be directed to the right place, but zero overlap between the forums is an unreasonable goal. I see nothing wrong with answering the easy ones in whichever forum they show up in. Rob is taking a slightly harder line than that in JP1 and that's his show, so I'm not going to argue it there. Here I think Daniel Tonks sets the rules and I don't think (correct me if I'm wrong) he has banned JP1 discussion.

Long ago I did a lot of USENET posting, so I know the basic argument that answering the easy but misplaced questions is a bad thing because it encourages more people to misplace questions. I don't see how that fits JP1 at all because the people who ask off topic questions there almost never read through enough previous posts to be aware (encouraged or discouraged) of how previous off topic posts have been treated.

Here, I don't think anyone will resist a gentle suggestion to move complex JP1 discussion to the JP1 group, because they will understand, once that suggestion is made, that they will get better and faster JP1 answers there. For the simple JP1 questions, I still think it is easier to answer them here than to redirect them.
