The Ultra Fractal mailing list is a great place to ask questions and to share tips or fractal images with other Ultra Fractal users. See www.ultrafractal.com/mailinglist.html for more information and instructions for signing up.
Warning: the mailing list generates about 20 to 50 messages per day. To make it easier to handle this amount of messages, you can set up your e-mail software to automatically place messages from the Ultra Fractal mailing list in a separate folder.
In Outlook Express, you can do this with Tools|Message Rules|Mail. In Mozilla Thunderbird, use Tools|Message Filters. Messages from the Ultra Fractal list always contain [ultrafractal] in the subject line, so that is a good way to identify them.
