Hello copyinfo,
At first I invit you to read SEBLOD forum rules that you can see on the top of forum index page http://www.seblod.com/community/forums and to respect them.
Do you think that you're alone to use Joomla plugins with SEBLOD? Of course not, so it's working nice in normal usage.
So please add more details about your case, which content plugin do you wish to use? Which version of Joomla and SEBLOD....
Regards
