Talk about and share drawings and art made with ASCII text or anything to do with the subject of ASCII text art.
To post a message with ASCII art, I've found that it works to use the Rich Text version of the Yahoo message editor, copy your text from a plain .txt file then in the Yahoo editor, select the courier font then paste your text.
This preserves the spacing when the message is displayed on Yahoo.
Figuring that out was actually the real reason I started this list. My first attempt to paste ASCII text art on another user group didn't work and I wanted to work out the solution without flooding my other group with my experiments. :-)
