Dang, stormy, don't stop asking questions! Even if someone says "do a search" or if someone like me gives you links to previous similar threads, we need questions being asked. You see the answers people gave you already? They may have already contributed to just such a question before, but that doesn't mean they aren't ready, willing and able to answer again.
Sometimes the search can be a difficult thing, due to the way you enter your criteria. For example, the spelling of asymetrical......spelled correctly brings up one set of threads, spelled incorrectly will bring up a whole different ball of wax.
This is cabin fever season......for us folks who live in hard water country or who are too chicken or ill-equipped to go out into the cold. We need new diversions (topics of discussion). Just look at our silly fussing and feuding over the "newest topics" hullabaloo.
For your viewing pleasure, I give you this link:
He, he, he. (evil laughter) Hope you have plenty of endurance to get through that one!
