Creating a list of volunteers

Hello all,

I am willing to skype or chat anyone learning English to answer their questions. I have skype on my phone and am available often. I am sure there are many who feel likewise. Is there some sort of list we could be added to if we want to volunteer in this way? I think it would reduce a lot of redundant threads and, as someone who knows how to make databases, if there isn't one, I can make one fast :)
