At another site I am involved with members make their own via www.makestickers.com
They settled on an oval of a certain size and each order their own. This is the oval they use: http://www.makestickers.com/customize.aspx?tid=7689
but there are others to be chosen from.
They use the same basic design but customize the top portion to include their names or other info. They make them in a variety of colors and one sticker costs about $10.00
Members can each have their own sticker made and even customize it as needed.
Here is the link to make a text based sticker:
Here is a link if you want to add a custom design in the center:
I could get copy of the forum logo and add it to this thread to be used on a sticker if there is interest and then members could add their user names of other info around the edge.
