Re: tranfer posts from another forum
Hi,
you need to check the old and the new table structure (use phpmyadmin) for this.
next you need to convert the old tables to the format of the new tables.
Learn from how bbpress will create the records inside the tables and import your old data this way.
I don’t think that there is a tutorial on how to do that (didn’t know that Joomla has a forum module)
