Your ministry does need a website, but bells and whistles aren't necessary. It's much more important to have an up-to-date website that's easy to read and navigate.
If finding the page(s) with campus ministry information is too complicated, requires too many clicks, or takes too long to load, college students will give up and not come back. Ditto if the information is out-of-date or inaccurate. Broken links are even worse.
If your webmaster isn't able to keep a weekly calendar up-to-date, for example, it's better to have a monthly calendar that's always current.
