One minor moan, well I am a pensioner :), bumping yes it can help but it can also be counter productive as if member sees a post has been responded to they may well pass it by.
I bump whenever I see somebody wants an answer.
I know how it feels to think you are being ignored when you really want the reassurance that somebody is listening, even if they can't help.
On the basis of what you say Ray, anybody who answers at all will "bump" the post and therefore nobody else will bother.
How do you know a thing has been bumped until you look at it.
Sorry, but I'll continue to "bump" http://community.prostatecanceruk.org/editors/tiny_mce/plugins/emoticons/img/smiley-foot-in-mouth.gif
