At 28th October 2019, YahooGroups started the shutdown of its forum groups, including the Psychtoolbox user forum.
From now on, no new questions or replies can be posted to the public forum website. All existing content will be deleted starting 14th December.
The shutdown of Yahoo’s services happened on such short notice that we didn’t have time to prepare in advance.
We are working to find a new home for the forum and will let you know here when it is ready.
