I was seeing today the challenge forum, (btw: some great entries!), and I started thinking: "...Hmm, why did I withdraw from this one?, I mean I sure had my reasons, but the real fact about it is, hell! I don´t want to only model...".
So I thought maybe there´s a good chance you could make the Challenge forum a bit more challenging

What does this guy mean?
What I mean by that is, Maya´s got hundreds of aspects that we could exploit for the Challenge forum. How about rigging? animating? texturing? dynamics? There´s lot´s of oportunities we could exploit.
ie:
November´s challenge is:
Animate this creature. download here (*mb)
It has to convey emotions, blabla, blabla, please post playblast files or blablabla ...
May the best win!
This is just an example, but I can see the possibilities, I mean with this challenge for example, animating and rigging forums would go crazy with questions. Imagine a Dynamics one?
Well, my 2 cents anyway, but do think about it.
