All of the options of WordPress inside the Joomla CMS. You really do have to see it to believe it.
There were a couple of bugs related to the new version of Jomsocial, but the support was great and a fix was made available in a timely manner.
Now, I can offer my members blogs that they can completely design to look independent of the site, while still having their articles posted to the main site blog. Plus, all blogs and comments post straight to the activity stream on the main jomsocial page, and show in the users profile as well.
Thank you, core php for this powerful component that helped me take my site to the next level. The feedback from my members has been overwhelmingly positive as well.
