Hi Tulip,

Here's how to stop Mozilla Thunderbird from asking you about the desired format when you compose a rich text message and click Send:

* Select Tools | Options (or Thunderbird | Preferences... on a Mac) from the menu.
* Go to the Composition category.
* Make sure the General tab is selected.
* Click Send Options....
* Under Text Format, make sure something but Ask me what to do is selected.
o I recommend Send the message in both plain text and HTML, which preserves any rich formatting while giving recipients a chance to choose a plain text alternative.
o Messages you compose in plain text only will not be converted to HTML.
o For people you know to disdain all rich formatting, set their preferred format to plain text. This will override your default choice, but only if the message has no other recipients set to accept HTML.
* Click OK.
* Close the options window.
