How do I insert a thumbnail image within a post? I can insert full sized image with no problem, but I haven't found any menu item for inserting a thumbnail.
You click on the paper clip at the top of the "Reply to Thread" page. That's an "attachment". There is a thread on how to do this in Support...somewhere. [edit] Here it is. Under Tutorials at the top of the Support Forum. There are lots of other neat things there, too.
