Hi, I think you may be misunderstanding my intent, I do not wish you to breach privacy and supply anything. Perhaps I can be clearer with my questions. Here they are exactly (anything not explicitly stated in the question should not be inferred):-
Q1) Is it possible to post comments on Word Press without a valid e-mail address. Yes/No
Q2) If Q1=Yes, Does such a user still receive notifications when replies are posted to their comments. Yes/No
Q3) If Q1=No, Can I assume that this user (who displays an invalid e-mail address) is getting notifications of my replies to his comment? Yes/No
As you can see I am just looking for Yes/No answers. Essentially, should I bother to continue to reply to his comment or is it pointless on my behalf because he will never know about it.
Hope that makes my query clearer - not asking for his e-mail (actually it never occurred to me that there could be any other e-mail address than the one I could see which was invalid).
