I thought I would make this thread for those who can't decide what forum package to use. There are many forum software packages available for download that are free.
My personal favourite forum software package is MyBB due to it's simplicity and complexity to the admins/mods and members. When looking for software packages most people try to find the most securest of software packages as many board owners worry about security.
Please vote for your favourite forum package and provide good reasoning if you can.
