CiviCRM Community Forums (archive)

I have 3 different contribution forms for 3 different membership types/3 different user types.
When they join the profile assigns them to the corresponding group in civi.

I would like each group member (as they join) to be automatically assigned to the corresponding joomla group.
The idea is when they log in they see different content information. e.g. students see scholarship programs, others see different articles.
Any suggestions?

In the profiles i have set:
Joomla user account registration option?   Account creation required.
Include Joomla user account information links in search results?   Yes
