Hi folks, I've been searching around for a solution to this but have not had any luck.

Structurally, I have 2 vocabularies, "categories" and "tags." Users are required to choose a Category and have the option to free tag the article as well.

I'm trying to find a way to get the top 5 or 10 "tags" used on nodes within a "Category" to display with the article listings of each vocabulary term, I've seen examples to show tags on the node level but haven't found a way to do it at the vocabulary level as of yet.

Ideally, I would be able to use something like Radioactivity to determine the most popular recent tags but I'm thinking that may be too much to ask right now.

Is this possible? Any thoughts on modules or snippets that could get me going in the right direction?

Thanks for your help,
Rob
