yes, and the only official path to the download page is via the email form; at this point, we have no plans to publish direct links to the downloads page. The key actually changes with every separate request I believe, I don't know exactly how the web guys have implemented that.
Again, the only link that we recommend for publishing is
www.scalix.com/downloads. Download for community edition then takes you through the email address form. Again, emal address entry is required, but not validated - if you want to put in
mickeymouse@donaldduck.org, feel free to do so; a good number of people choose voluntarily to give us their real addresses, because they have a real interest in the product.
We are a commercial company and we need to make money by selling off licenses for the commercial version of the product as well as support and services. I do think we provide a lot more product value at no cost than anybody else in our market. I don't think it is too much to ask for some information in exchange, for statistical purposes and also to provide you with good-to-know information about our product range.
I will edit your posts and delete those links as I find re-publishing them here inappropriate.
Florian.
