I have posted today and some period ago but my posts have been deleted (I have searched my posts by search option but only two posts appear but not those which I have posted recently).
Please tell me why?
How exactly did you do your search? If I go to the Search functionality and type in your name under Author Search, it shows 9 different threads which you have replies to.
If this is the method your tried, and you only got 2 threads, I am guessing that you unknowningly had other criteria selected in that Search option that limited it more than you intended to.
