I have tried to send a sticky mail with my HTML code included; however, I received an error message that there was a "style code error...continue editing...message not submitted." The reason for the sticky mail in the first place is because W3.org has indicated the code error and I need help making the correction for validation. I see the "style codes are on" notice in the sidebar so is that a function I can change in order to include HTML (or CSS) code in a sticky mail? Thanks.
What you can do is put your code between [code] and [/code] or between [quote] and [/quote]. In that case the Sticky Mail system will not try to understand, format or parse your code, but just accept it as plain text.
