Facebook neewb query

Zylahe

So i realise i'm a little late, but i've just joined a facebook group .
There is a weekly evnt and someone posted a question on last week's occurance.
I now have a question for this week's occurance.
Do i post a new post or can i just add a comment to the previous post?

I hink i am asking "Do you read all the new comments, for a weekly event that has already happened?"
