What's one website feature you wish every forum had?

I've been thinking about the little features that can make a forum so much better to use.

Whether it's a handy notification system, profile customisation, a good search function, reputation points, or something completely different, there are plenty of features that can make a community more enjoyable.

What's one feature you wish every forum had, and why? I'd be interested to hear what other forum owners and webmasters think!
