Not to sound like an ass, but this is a perfect example of what I was talking about in my
post on the email support topic.
You wanted to know about Absolute but made no mention to Absolute in your original post. This is my exact point as to why I don't believe people most of the time when they talk about email support being bad, because most people aren't clear as to what they want from the start.

As to your question, as far as I know you can't but it's been some time since I played on Absolute so I'm not positive. I can't ever remember seeing card mods for Absolute though.
