No problems, feel free to wonder and may I can explain a bit... I'm doing that just for the pure reason that many of users here enjoy it that they'll be remembered in their birthday.
I'm not either the inventor of this birthday wishes idea nor know where it actually stemmed from. Another user ran that before me but she wanted to quit and after noticing that I had answered these threads pretty often, she contacted me and asked if I want to continue her path. I know that many of these congratulated users doesn't seem to be/aren't active here but since I cannot know who actually is and who isn't, I just check the Horseforum calendar/birthday thread daily and go per it. The Horseforum Team knows about that and actually had made the 'birthday queen' job even more visible earlier. May some of you remember my (and my pregessor's) birthday cake icon next to our usernames and the 'birthday queen' status that we had back to times.
