Hi Andrè, thank you for answering, there should be no need to copy and paste quotes between pages, this shoud be remembered by the forum itself, I can do this in older forum platforms on other forums.
I'll explain every step, it is very simple:
1) I clicked "Reply" on the post I'd like to quote on page, let's say for example, 20;
2) I wanted to quote another post on page 21 and so after step 1 I went to page 21 and clicked "Reply" under that second post;
3) By doing this I lost the quote of the post on page 20, then I went to page 20 again, quoted the post and copied it, I went to page 21, pasted the quote and quoted the second post.
I'm pretty sure that in the previous version I shouldn't have done that. I don't know if it is possible but we should be able to quote post on page 20, go to page 21, quote the post on page 21 and having both quoted in the new post.
I hope I explained better what I meant.
