Downwind, it's generally considered bad form to cross post since multiple people end up answering the same question without knowledge of the others. It leads to fractured topics & wastes people's time & effort. For example, this topic of yours has the same answer from three different people in three different forums.
May I suggest a better way? If you're not sure what forum would be best use your judgement & choose one. Post your topic and wait. Sometime answers are few, sometimes many, other times someone will suggest a better forum. You can then close the current thread, leaving link to your new thread in the other forum.
