Expression3 is open to users of Creature House/Microsoft vector graphics program Expression.

The object of the group is to enhance learning and use of the program by sharing tutorials, files, and graphics made in Expression.

To this end, attachments will be allowed. Members are asked to limit the size of attachments to 150k so that those with slow internet connections will not be swamped with bandwidth.

While it is possible to join this list and either read posts online or to receive them in digest form, it is recommended that list members set their preferences to email in order to receive pictures, strokes, tutorials, and the like. Yahoo strips all attachments from posts received in digest form.
