I've been using the RSS2 feed that WordPress outputs to make a sort of "What's happening" section on the front page of my site. Utilizing MagpieRSS, it's working pretty well. The only problem I have, and it's rather negligible, is that the categories in the feed run together: IE, I have a category of Tech and a category of Web Standards, and say a post is cross-listed in both. On my main page, it shows up as: TechWeb Standards. How would I go about altering the RSS feed to perhaps put a space between the categories, or perhaps even a space and comma?
