I love SMF free forum software as it's simple to install and the admin interface is easy to use. There are many good mods available for SMF to customize the look and functionality including anti-spam and even profile page customization. Recently, they've come out with some very decent SMF themes that compare with what you might find for MyBB. Though it's not as good as a paid software such as Xenforo, the forum software does serve the same purpose for having a forum especially for someone on a limited budget. Have you tried SMF free forum software? And, if so, what are your thoughts about it?
