Does anyone know of a good resource for getting information on openings of photography shows at New York City galleries and museums?

I'd love to get periodic emails, but short of that, a web site that I could check every once and a while would be great.

Thanks.

got this from a friend:

whitewallmag.com has a weekly list of openings which are pretty consistent. Also artfagcity.com +nymag, ny'er +TONY
