We have updated the site.
Many things are small improvements, but things that you as visitor will notice mostly are:
For registered users the download options are improved. We had to add a waiting time of a few seconds to prevent bots from causing too much troubles. With a new update we now are able to set seperate waiting times between registered users and unregistered users (which bots are).
So, we could now set the waiting time to a minimum value.
For unregistered users also some things have changed: Unregistered users can download a maximum of 3 files or 25 MB every day.
If you want or have to download more, then you have to register.

Then we have added more selected products to our store. We hope that it helps to point you to some interesting books and video's for example.
