Dear Janice_h,
It's still basically spam to keep pointing us to your site--which in this case has a whopping three replies--from a year ago--the first reply of which says to come to this site to browse.
We weren't interested in your site the last time someone tried to sell it to us by starting a thread. I seriously doubt that we will migrate en masse this time through your little breadcrumbs that appear to have a logical link, but still suffer from the problem of too few people who blog instead of discuss.
