Currently I am using Joomla. I would like members to have a community, where they can post Blogs, Wiki's and they could then be viewed by non members and members. Also for current amembers to login into a discussion board, which has the ability to let members and non members reply to posts by email too. Also a profile page, which allows members to search for others members, area and have a group of members, if they choose to, to be searchable by non-members. I know a joomla plug in exists but would it carry there information into the other system(s)?
