A couple of interesting points.
The first is that they have my address wrong - Enniskerry, Dublin, Dublin, Ireland, so now I have to trawl the databases to find where that info is wrong. And if I write to them to correct it, they slam me for €1000. Maybe it's a cynical deliberate error?
The other, which is more worrying is something I noticed in the pale [hard to read] print on the back. By my understanding, they reserve the right to place an ad against your listing, which you are supposed to provide the content for.
However, if you do not provide any copy, they reserve the right to write their own copy. So Blacknight could end up with a nice banner ad for "black lacy nighties". And there is nothing you can do about it without forking out the €1000.
The only redeeming thing about all this is that I can't see their directory becoming the definitive Golden Pages of Irish business
