Hey, you can use bridge for joomla 1.5 -----?
There is no officially supported bridge for Joomla 1.5
(actually, there is no officially support bridge for joomla, period.)
Try JFusion buddy
Marking this as solved as there is no supported bridge at this time.
Jfusion does work pretty well when you use SMF frameless for Joomla. Dual login works! But logout on SMF doesn't log you out from Joomla. The Jfusion developers did a great job ;)
