In the past few days, we all experienced problems downloading the tutorials and the recent siggy list. While checking the situation, I discovered that I stored those files in an unsuitable folder of the website. I moved them all to the submap where they should have resided in the first place.
I successfully downloaded each and every one of the files with my laptop as well as with my wife's iPad. Please retry the downloads yourself.
I apologize for any inconvenience this issue may have caused you.
