David,

>Granted, there are cases where we don't know what email program a recipient will be using. But there are a few cases where I know for certain that all recipients will be running Outlook 98 or higher.

Get wwIPStuff from www.west-wind.com and don't worry again about what email program your users have. Sending HTML email is as simple as (remove spaces added around tags):

cHTML = "< html >< body >< h1 >This is HTML< /h1 >< b >Test.< /b >" + ;
"< /body >< /html >"

loIP = CREATE("wwIPStuff")
loIP.cMailServer="your.ispsmtp.mail" && smtp outgoing server
loIP.cSenderEmail="youruser@theirisp.com"
loIP.cSenderName="Your Username"
loIP.cRecipient = "recip@recipisp.com"
loIP.cSubject = "HTML email test"

* here's the key
loIP.cContentType = "text/html"
loIP.cMessage = cHTML

loIP.SendMailAsync()
