All comments are finally back (except the comments made via haloscan between Januar 21 to 30st) - with the hard work of Andrew Koushnir and some help from Khris Loux and Chris Saad. Thanks!
Your comments - back to 2004 - don't show up right now, but I hope that somehow, sometime I can bring them back. Why?
I trusted HaloScan, with whom I worked several years on the old Blogger. With the new Blogger I didn't need their service. Than I saw last week that they have an easy automated service to add Trackbacks to the new Blogger. I trusted HoloScan and used last week stupidly their routine on all my public Blogs to add Trackbacks into the template.
Unfortunately, with this process HaloScan prevented all earlier comments to show up and they deliver with each post a piece of advertising (I have not agreed on).
I didn't see any warning that my old comments would disappear, that advertising would be delivered and when I asked them to rollback / restore the old template, they where quite responsive and friendly (by eMail and Twitter) but it seems they don't know what they change and how they change the template ...
So be patient, and beware from using haloScan's / JS-Kit Service before they solve my / their problems and know what they are doing.
The user-forum is closed, support is eMail only.
no action at all from Khris Loux and if you look at his tweets, it seems to me he doesn't care
It looks like that Chris Saad has not much influence at HaloScan / JS-Kit Support
twice via Twitter @chrissaad told me that he makes sure that our problem will be solved ...
