OK after some rooting around, I think I have a link combination that looks identical in both. I hope you've noticed the change and that it is for the better.

The first change was to find...
/* General font families for common tags */

In this section I changed the a:link, active and vistied colour to the ones associated with a.postlink:link. I also changed a:hover colour to match the one associated with a.postlink:hover.

With the colours sorted I simply added a a.postlink:active tag as it appeared to be missing. Hence now both forms of tagging should render identically.

Could everyone confirm that all forum links are now ok.
