The threshold for automatic approval of posts to MSAR-Riders is
now set at 5KB, which is about two printed pages worth of text.
Most posts that exceed this threshold do so because they are
spam or contain a virus, duplicate copies of the text, or much
unrelated text quoted from other posts. I try to spare all of
us from such annoyances, but the downside is that sometimes a
legitimate post gets held up until I can deal with it. Sorry!
