Namaskar Sunayna ji,
This is a very pertinent question. I expect anyone could have posted such a concern, not necessarily me alone. Now my explanation is as follows:
1. CHR - I think CHR is the boss of citehr, and even though he may have been absent from the forum, I could not have enquired due to my humble position as a member here. However, the absence of CHR is not correct. He has posted on the 2nd and 7th of December last.
2. Ajmal Mirza - I do not remember if I had any interactions with Mirza saheb in any thread. So this is due to my lack of contact with him.
3. Numerouno - I believe I have had about 4-5 interactions with him in total. I always appreciate his posts. His posts are consistent, never abruptly disappearing. On the 22nd, he made a post in the life and livelihood thread.
4. Shoonya - No comments.
5. Rajat Joshi - I last interacted with Rajat ji on December 1 in the Creative Visualization thread. He had also mentioned in a certain post that he is otherwise busy. He has posts on the 2nd and 8th of December as well.
6. Sunayna - When Sunayna ji was absent for a long time, I remember expressing concern and discomfort, of course, in an ongoing thread. She replied upon her return.
I trust the situation is clear.
Regards
