Thanks for your reply Switch.
I have pondering about what you said for a few weeks, exploring some addons that extend content control and generally wondering how we could use the power of the native Joomla content system itself rather than having to add a new blogging content component.
So far my thoughts are moving more in favour of using the Joomla content system itself and trying to figure out a way where authors can only post their articles (blogs) to a certain category. I'm test driving JACLPlus for this purpose at the moment and will report back my findings if they are of use to the discussion.
As far as displaying members blog content goes, I see that as being done quite simply through the existing blog frontpage display. And with Community Builder installed, members can view others member profiles to see a listing of their latest content submissions.
I am not so sure about the need for individual categories for each members blog articles, and still sitting on the fence as regards to that idea. The other main issue that I am pondering on is how I could create a custom submit link so that members new submissions are automatically posted in the correct place.
Another random brainwave I had was if it might be possible with the CB content tab to customise it so that only members articles from one particular sub-section would be listed in there.
OK I'm all pondered-out now. Thanks again for sharing your ideas
