Let's try that again.   (Obviously, I'm a relative novice at this.)

If I type something like this,

Welcome Chez Mudcat,
DeanMeister

in Composer, and I go to to the "Page Source" view, it's got all sorts of HTML code around my text.  I just cut from the paragraph code right before my first word to
the exclamation point at the end, and paste that here, and I get the fancy-schmancy post above.

(Maybe a clone will zap the screwed up post.)
