mysql >=4.1 required (Bugs)
I just wanted to remark that mlf2beta5 doesn't work with mysql-versions below 4.1, because of a different timestamp format.
furthermore the collate specification used in initial.sql (utf8_bin) doesn't seem to work with older mysql-releases either.
perhaps you should notice this in your documentation.
I think, it would be best to use unix-timestamps to garantuee compatibility.
what exactly are the advantages of utf8_bin compared to utf8_general/_unicode?
why not use utf8_general_ci (default setting)?
