Ok, I've been out of here a long time, but I am seeing everything is better than when I left. I like the new reconfiguration of the Homework section. By the way Arildno et al seem to be spending great amounts of time on tutorials. I think we should advice Administrators to broaden the diffusion of this web site to scholars over all US. I mean, I know it is diffucult to reach the ears of every people, but maybe many scholars don't know this forum is existing. To say the truth, and trying to saying it in a kindly way, my personal opinion is that the administrators don't realise of how good is this site compared to other ones. If I were the administrator, I'd try to diffuse this site through every school of US (that's a business thinking). I am not intending to extract money of this site, only to enlarge it and spread it as more as possible over the webworld.
