Bernard - not sure what you mean? If someone wants to critique my published work i.e. a critical commentary - there is nothing that I can do - other than respond to it with a counter-critique.

Thanks for the reply Dean Whitehead

Perhaps it was a bug at ResearchGate yesterday but it was, at a moment, not possible to add comments about a publication.

They do seem to have removed the ability to find comments one has left on someone's work. One has to record or remember the publication and go back to them that way. Right?

This seems perfectly true, Matthew Elvey .

The search process under these conditions becomes very tedious.
