nope. Can’t smell anything 🙂
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.
