question about online property auction in Michigan

Hey, there … I’ve been asked to help a friend of mine spread the word about an online auction of 13,000+ tax foreclosed properties in Wayne county in Michigan.

This isn’t a post intended to spam the board. Fact is, I have a whole press release in hand about the auction – but I’m not gonna post it here out of respect for the forum members: I’m active on several forums (not real estate; tech and music), and have been for about 15 years, so believe me: part of me is sorta cringing at making this post, because I know all too well how newbie posts are most often received.

My question is this: Where are the most appropriate places online to spread the word about an auction of tax foreclosed properties like this? I’ve contacted Real Estate reporters one on one from various examiner.com sites around the country (and received some nice feedback), I’ve posted some information to appropriate Facebook and LinkedIn groups – but the last thing I want to do is post willy-nilly to every possible real estate site on the planet. I’ve been in online marketing communications since AOL was charging by the hour, so I’m all about quality, not quantity. So I figured you all know this market far, far better than I ever will, so … well … here I am.

Any recommendations are genuinely welcome and appreciated.

Thanks for reading.
