I jsut wrote this in another post, and thought I may as well request it:

I was thinking about this the other day. It seems to me that Joomla itself is a blogging system of sorts. I would very much like to see a plugin that takes advantage of this. My idea is as follows.

The plugin creates a new content section called - user blogs.
When a member registers a new content category is created with their username as the title. Thus every member has a content category in the section - user blogs.

Thus it is a relatively simple addition to create a submit new blog entry tab, (this exists already in Joomla!) and a display recent blog entries tab/view all entries tab (with pagination) This tab would just pull content from the user's category. Easy

Only one real hack, to only allow the users to submit to their own blog.

This is all using Joomla standard features, just combining it all in one place. The only downside to this is that the user cannot create their ownsub categories (due to the restricted hierachy of categories) unless this was hacked using jacl or whatever that ext is.

This should be a relatively easy job for someone who know's their way around Joomla!

Just my 2 cents
