I went back and checked the link this morning, Lynn, and you are right, it is correct. The URL Bob reported above is clearly missing the http://www.elta.gr
so it certainly wouldn't work. Even if you add that, however, it is still a non-existent page. How it became corrupted when Bob tried it I have no idea, hence the alternative routes.
I am aware that sometimes links don't work when somebody else tries to use them, which is why I sometimes start with a home page and describe the steps to get to the wanted page. If I go through the steps myself until I get to the key page, then copy the link and post it, it sometimes doesn't work if somebody else clicks on it while it continues to work for me. For example this is the page to get into the system to pay car tax: https://www1.gsis.gr/webtax2/telhkykl/y ... /index.jsp
I think this link will work for everybody. All they have to do is click on the ΕΙΣΟΔΟΣ button. This is the page that appears when you click on the ΕΙΣΟΔΟΣ button: https://www1.gsis.gr/webtax2/telhkykl/login.do
I suspect, but don't know for sure, that if somebody else clicks on that link it won't work for them? Perhaps somebody could try it and report back? Especially somebody who has never visited that page before.
