I clicked a link that someone posted to an Adobe forum. It changed my sort order from Latest to Relevence, because 'relevence' was one of the criteria in the URL.
Clicking on a link should never change my preferences.
To clarify, I don't mind a link showing me a specific setup, but it shouldn't change my defaults. When I go back to the specific forum, my preferences should take precedence.
All links to actual Forum main pages in these forums include the Sort order selection.
Here are mine for the forums I have on my Bookmark Bar.
Note the word "latest" in both links above.
You clicked on the link for the Experiment thread in the ACP forum and that chaneg YOUR Sort to Relevamce. It did it to me also.
Once you change it back in any forum it stays like that.
That's what I said.
