Are there any new developments regarding this issue?

This would be EXTREMELY helpful! I cannot tell you how many times my colleagues have asked if there was a way to do this? Also helpful, would be a toolbar with simple editing marks (delete, insert, break, etc.).

It is unbelievable that such an expensive tool as Acrobat X does not provide a simple command to make all comments anonymous. Sorry, but it is not good enough to thank for the suggestion. Adobe staff should have thought of this in the first place, since this is an obvious need for thousands of scientists and Adobe should now rush to provide the needed tool. Current behavior (latest Acrobat as of this writing) is a mess, since it requires to edit every comment, every highlight one after the other if one has accidentally annotated it non-anonymously. And then what a mess results, since the program behavior is buggy and Acrobat changes not only the author but also the appearance of a highlights, although I edited only the name. Incredible stupid program behavior for something as simple as a global replace text. Shame on Adobe!!!! Simply inacceptable.

Thanks for your help and cooperation (in case you should read this).

Sincerely yours,

I struggled with this at first, and read all the various comments and suggestions.  However, the ultimate answer was relatively simple using the free Acrobat Reader X.  I am using version 10.1.2.

Open the file with comments.  Click "Comment" in the top right. Left-click once on any comment to highlight it.  Use ctrl-A to select all comments. While they are all highlighted in the comments window, right click any one of them once.  Select properties from the context menu.  In the Properties dialogue box that opens up, switch to the "General" tab.  Delete the author's name in the first of the two fields.  Click OK.

That's it.  All comments now have a blank instead of a name.

Am I missing something?  it seems very straightforward!

I have done this hundreds of times (i.e. click the box to make this the properties default), and is it has yet to work for me. I wind up doing the options for every single correction to remove my name. I agree with the individual who is highly critical of Adobe for this problem. What appears to be a very simple correction just does not work.
