I have always used the My Stream section to find out who had commented on any of my gallery items and then would thank them.
However, today I happened to visit one of my cards in my gallery and noticed a person had commented on my card yet they weren't showing up in My Stream/Activity Stream that they had commented on my card. Yet the person before and after them were showing up in the My Stream/Activity Stream.
Any idea why?
Also, if I have missed thanking anyone for commenting on any of my gallery items for this reason, I do apologize.
Thanks in advance for any assistance.
