I've recently upgraded my company website (www.pgmkr.com) to DNN7 to test everything out before upgrading any of my clients. No major glitches, but one annoyance - the headings on my pages (e.g. Welcome and DotNetNuke on the homepage) are displaying with lines below the text, which they did not before I upgraded. I have not changed the skin, so it seems to be something to do with how DNN7 is rendering the <h2> or <h3> headings, or how it's interpreting the classes. I've looked at the source and the css, but haven't been able to find a reason for this. Any ideas?

Thanks Greg. Odd that this didn't happen with DNN6 - same skin, so the line must've been there!
