A. Yes. You can use ispell for this. In Common Preferences, in the spot where you can define an alternative editor (as long as you do not use that, of course), you enter "xterm -e ispell %s". Do not enter the quotes. With this set up, you can have spell checked when writing an e-mail by hitting the "Editor" button in the compose window. Note that you can enter the xterm type of your choice, so wterm, eterm and aterm should also work, as long as they are installed on your system.
