I think any website, whether unique or formatted, can serve as a wonderful PR tool that'll generate interest from PNMs. I think, that as long as you avoid certain color schemes, certain fonts, and spelling/grammatical errors, then your site can still have that professional look while being unique.

When I did my chapter's website a few years ago, I wanted to make different pages with different looks...and in the process I realized that I'm not going to be maintaining the website forever, and so I changed everything in order to make things easier for the girl taking over the site after I graduated.

It's a good thing I did because the handing over of the reins was hard...I went alum in 2002 but I wasn't able to hand things over till this past summer. The my successor was glad that the pages were simple to update and maintain!
