Yes I was thinking of this recently. Here is that :
Bitcointalk (India) I have never created a TG group, if anyone have problems in joining just PM me.
I joined the TG group but i am not able to see anything but the user who invited me says that there are contents and forwarded the screen shots and i am not sure why i am not able to see any of the conversation.
Since the group is not super-group, you will not see messages prior to your joining, only those messages which are posted after your joined the group will be displayed.
