I really like the HTML feature on Entourage's email program, where you
can choose your font, font color and background color, etc.  I use it
when I send out, for instance, party invititations to a whole list of
friends. I always send it to myself and list everyone else as BCC's. 
Recently I discovered, though, that when I look at the message I sent
to myself, some of the lines of text that I tried to make into a
larger font come out in fact smaller than the rest of the text.  To a
visual perfectionist like me, this drives me up the wall!  I've tried
saving it before I send it; doesn't work.

Life is too short for fussing around with minutia like this, I think.

But does anyone out there have a solution?

Have you tried www.evite.com?

this looks somewhat promising, actually. I had another question, which
went almost nowhere, at:
http://answers.google.com/answers/threadview?id=444441 . . . . no
stars for those comments, folks!

so, Nelson, got any good links for regular e-cards?

I like greetings.yahoo.com
