Apparently, I have had an issue with the registration system, both for my shop and for the newsletter. If you have tried to register and didn't get a confirmation, it probably failed. Please register again using another browser or drop me an e-mail to juha@liteplacer.com and I'll add you manually.
My apologies for the inconvenience!
If registration still does not work, please, please let me know.
[Edit: Orginal post claimed the issue had to do with Safari. In fact, it was a cache issue and affected all the browsers I am not using. Nasty, because it started to work every time _I_ tried it.]
