Is the XtraCAD SIG on Yahoo Kaput?

I was whipping out an new idea for the Rock Ridge and Train City when I discovered that XtraCad doesn’t have a roundhouse object. So I just thought I’d go to Yahoo, find the SIG and get a download.

Guess what, the link form the XtraCAD homepage didn’t work so I searched Yahoo and it wasn’t there either. What happened? Is it me?

Anyone have a URL?

Here is the link to the Yahoo! group: http://groups.yahoo.com/group/XTrkCad/

Walthers N scale Union City Roundhouse is in Xtrkcad.
