i do with the trim '-'
periods don't make it thru the preg_replace for non-alpha
also, the problem is that not everyone calling make_ubb_url asks to have the $title sanitized
a real re-work is in order for maybe next version.
edit: as to the "Re" dealio... the real way to do that is to not have an indexed title for every post. the topic should be enough for the entire topic. this would cut way down on space as well as leverage big improvement on full_text searching on topics. my pre alpha 7.6 version does exactly this...
only losers will be the 'show threaded' peeps, who like to allow changing topic in mid stream
