[pLog-svn] questions on blog categories and global article categories

[nick nizhenyuan]

"In my opinion I think it's enough if we allow only one
blog category per blog and one article global category per article"

The reason why we have global article category and global blog
category is that the BSP want to organize the blogs and articles.

Based on this reason, just as you said, one blog category per blog and
one article global category per article is clean and enough.
