"Most systems I use allow editing and don't have problems with abuse like re-writing history"

Of all the MBs I've ever visited, I've never seen anyone BOTHER to 'rewrite' history as some here are suggesting... I'd imagine that if anyone did, simply no one would bother replying to them, and their posts would fall off the page...

Oh... wait... this is mudcat... I forgot...

You're right... it'd happen all the time, and people would spend hours a day wailing and gnashing their teeth about it...

Ya know... just like now... So, I ask for those who are against/afraid of change, how would it be any different?
