Nice to see you on the forum after a long time !
I hope they are still working on renewing everything...
I am still missing about half of my projects also..I searched for you for music, minipops, string, synthesizer, opto, frankje and no result.
Even on my own name: no result. Their search engine is not working very well I think.
Did you not receive an email early september about their new website?
It contained the following warning: (quote)
