currently uses boonex community building software- both dolphin and orca. Specifically I am looking to be able to allow a visitor to post a question without registering- as this site does( see left column "ask the community)
Since I am already a joomla user and i would like to do something similar- I figure CB is my best bet.
Thanks for the help in advance and look forward to being part of the community
