Displaying links list left to right instead of vertically?

Hello,
I have a separate links page on my site, and several links categories with a lot of links in each. I want to display my links left to right instead of in a long vertical list. I did this in prior versions of WP by having the link manager place a ‘.’ in between links instead of <ul></li> etc, which displayed like this:

Link Category
Link . Link . Link . Link . Link . Link

Next Category
Link . Link . Link . Link . Link . Link (etc)

I can’t find a way of doing this on 2.3 however. I’ve tried different template tag settings but whatever I do it stays as a vertical list. Can anybody help?? Many thanks!
