No line breaks between links

I searched for a similar topic, to no avail.
I’m trying to remove the link breaks between my links on my blog. It really stretches my sidebar out, and I just want them next to each other, hehe. Anyhow, how would I do this? I tried adding display: inline; to my menu id in my css file, but it didn’t work. Any other suggestions? Thanks a lot.
p.s. my blog is at http://pink-champagne.net/blog for your reference.
