As I have recently had bandwidth problems with the WordPress blog engine being installed with my Joomla! website, I’m currently testing Joomla! blogging components. The first one I got a hand on was Joomblog. Unfortunately, I can’t seem to let it run.
The nex component I installed and currently am testing is Mamblog. It seems to run smoothly. Just a little tweaking here and there today and I think it would be an alternative to WordPress.
