Categorising Myspace Blogs under my own categories?

[Jessxin]

Hi! I'd like to know how I can categorize my myspace blogs with my own categories. For example...if I have 100 blogs, the ones with regard to science, I categorise under "science", or the ones with regard to politics, I categorise under "politics", which would make it much easier to find, as the number of my blogs increase.

Thank you for your help!
