thanks, ib. of course, this is probably not going to be a habit with me. just the tagging thing is so unclear, and, they way spike explained it, it seems as if any post that raised emotions could be considered as "tagging", and the writer could be "poofed". so, i want to be really clear on what it is. just in case i EVER post a thread that could be considered controversial. not, that that is likely to happen, right? in the meantime, i better be good and stay in the rhino forum...oops, that might not be an answer, either...i'm pretty passionate about my nurbs, doncha know?
