Same thing happens to me and to others. Don’t take it personally. There are so many new threads popping up to the top of the list that old ones fall into oblivion.
(Check my profile, for example. It lists the threads I replied to. Many have no further replies and, of those that do, most were not to me. )
Continue posting and watch as you get more and more replies to your posts.
I started many threads that had no replies, on the other hand some of my threads had hundreds of replies and one of them is way past 2,000!! and still counting. So do I smell on some days and not on others? No, Sometimes even a very good topic falls of the page while other ones have more luck.
and commonsense, After you log in, you should see on top of the coffee room page “Welcome, commonsense” Click on your “name” and you’ll see your profile!
