Hi Michel,
Don't know if others feel the same way I do, so here I go.
Many times reading some messages, I would like to say
"great reply", "nice to read this" etc. Sometimes I make a reply and say that, sometimes not, because think will be spoiling the discussion. Some other times, the opposite ("what a bad reply!").
UT has a scheme that enables the originator of a thread to mark it as a help or a solution giving starts to it. What do you think about having a points system that anyone, that reads a message, could give points (negative or positive) if he/she finds it worth of that?
Regards,
Fernando
