Welcome to the SMFH downloads section of the site. Here you will find modifications for SMF from members of this site. Keep in mind, if we do not have permission to host a mod or a theme you will not find it here. We will be able to direct you to where it is though.
Also, some of these mods may be works in progress (WIP), which is to say they may have bugs in them. Ask on the forums for more information.
