Serendipity Forums

I've checked out a few other sites using Serendipity and I've noticed on one or two of them a "Links" section in the side bar. Is this done via an existing plugin or did they write their own? Or is it done some simple way that I'm over looking?

They wrote their own, in the HTML nugget - would be my guess

See I knew I was overlooking something obvious. I'm an idiot . In my defense though I have been looking at a lot of different systems and there was one that had links database module so I was thinking along the lines of that information being stored in a database. It's a weak excuse but it's all I have right now.

Thanks for your answer and patience with a silly question!
