Star Office and newsgroups

[Hermit]

I am running RH 6.1. I recently installed SO5.1 and it is running flawlessly. In the newsgroup section of SO, I subscribed to 2 newsgroups. Somehow, someway, about 30 newsgroups appeared. What I cannot seem to do is delete the newsgroups that I don't want. Anyone help me with this?

Thanks,

Hermit
