TOPIC: Link in notification email?

Hello guys!

I was trying to insert the links in the text of the notification emails.

I insert link http://vtokyo.ru/something
first everything works fine and emails come with the proper links, but after a while I open this message again and see only "/" or something what was added after /
say, the link was
http://vtokyo.ru/about
Instead of it I have /about

Is it something about joomla?

P.S. It works several hours or even days, but then disappears

Thanks
