Found the macro - $macros.Gravatar($comment.Email, $comment.Name, $comment.IPAddress, "%{size ='60'}") - Otto R. Radke
Argh! Comments migrated from dasBlog don't have IP Addresses, which causes an NVelocity.Exception. - Otto R. Radke
And now it is fixed:
#if($comment.IPAddress)
<br/>
$macros.Gravatar($comment.Email, $comment.Name, $comment.IPAddress, "%{size ='30'}")
#end - Otto R. Radke
Thanks for the listing on the showcase. Here’s where we are currently at with the site http://kevintunis.com/projects.... We are working on bringing more live streaming on coding including appearances from other developers. If you are interested in a guest slot contact me at Kevin@knowledgemgmtsolutions.com - Kevin Tunis
