Thanks for reviewing my thread.
I did opened many threads. For all threads, I click notify me of replies under additional options.
In my profile settings also, I turned this option ON.
I did not receive any emails about replies, but when I showed up to forum, I found many responses to my opened thread. :( :(
What is going on ?
The forum software has been borked for a long time. In addition to what you mention:
1. The erroneous error messages when starting a new topic that causes many posters to post again and again and again .......
2. No notification of private messages received.
