I can't find a suggestion forum, so I'm putting this here.
Recently we've seen certain members who have a liking for deleting their comments after a few days or when a thread doesn't go their way.
I'd lke to suggest a time limit on editing comments - say 2 hours, that's long enough to see you've made a typo and need to fix it or that you need to add to it.
Would also like to suggest a suggestions forum!
