I have installed some modifications on the forum. Some of them you should notice immediately.
Others have been downloaded, but have not been installed yet. SMF is a b***h in that some modifications can change up the core so much that other modifications refuse to install. So for these ones (and there are quite a few), I'll be installing by hand.
(P.S. this includes the custom bbcodes mod, "custom bbcodes" being a general term encompassing all bbcodes not included in default SMF including spoiler)
