The major hacked parts are the NS-NewUser and NS-YourAccount parts. This due to the fact that we needed to synch the registrations and changes in the users account with an external database for "short message service". We use XML to synch the data. A very ugly hack, but it works. The users can not become users unless they have a cellphone with short message service.
The website is secondary to the SMS service since the "members club" is mainly SMS based. The web acts as a easier way to handle them and to publish things towards the members.
Please note - the site is only in swedish.
