Fedora & Forum
It is so wonderful that you can find any large or small packages in fedora extras, but there is not any package for forum in Fedora Extras Repository!!!
May be I have to go and work on it. A Fedora Server should have a forum application on it. (It is only my oponion!) I think a suitable choice to add to fedora extras repository is Phorum. But first of all, I should check it with a master like Roozbeh ....
