Per the latest Bordeaux Village News, the HOA website is up, albeit still under construction. It's here: Bordeaux Village Home Owners Association.
There was a forum available when I first looked at it on Wednesday, but it seems to be gone now. I'll go ahead and keep the Yahoo! group running as long as necessary.
The new site has a lot of nice features including an option to pay HOA dues online and a section to download the latest newsletter in PDF format. Nice.
