My thoughts exactly. During my 10 years here, most of time I've been part of various signature campaigns and I can't remember myself counting words or symbols in my post. Why I would need it? I never thought whether my post is long enough or not to be counted by manager. But maybe for these who are looking into signature campaigns as one form of labour, it might be useful.
So, this script isn't for me, but still I think that OP have done good job. By making such thing he is gaining more experience as developper.
