OK, I'm reasonably proficient in HTML, but had not seen this tag until today. I came across it on a site running the Invision forum software, only because it is not rendered correctly in Firefox 22.214.171.124. IE 6 and Opera do display it correctly. Does anyone have a link to details on syntax, etc?
