First you gotta sign up (free)
then you gotta pick your catagory and decide on how you want it to look on your site ... then...
I hate to tell you all this .. but .. yep .. the html doesn't work right in msn groups (what a shock )
so you gotta "copy and paste" the whole preview into where you want it to be .. let me point out .. you signned up .. you are legally allowed to use their content and are by-stepping there html code that "should" work but doesn't in msn groups , in other words you are allow to "direct link" to their content .. they are hosting it . With all of the changes msn groups have done of late .. you'd think they'd improve their html lol.
