IE Upgrade popup modification

[sgadow]

I have a joomla CMS and i downloaded this free plugin to notify viewers who have IE6 that they have an old version of IE and to upgrade etc etc.. I don't know much of anything about PHP coding and I would like this to display in IE6,7,8 not just IE6.. would someone who is more knowledgeable than me be so kind as to make the changes required?
