Great hack Mutt! Thank you! The Avatar Addon hack is exactly what I needed. I had previously installed the Pulldown Image hack, which never worked correctly in Netscape. (Netscape behaves badly when a DIV tag is inside a FORM tag block).
One section of the instructions caused me some trouble. I was able to figure it out though. Take a look at
this file to see what I did to install this in UBB version 5.44a.
