Yes. Replying with multiple quotes is indeed a bit trickier since the recent update but as MB1980 says, still possible.Can you quote multiple posts on replies? Never done it before and there are so many having a crisis on here...
You can also copy and paste the text out of a post and format it as a quote using one of the icons. Or you can just hammer it in as code if you feel like doing a bit of programming
Tons of options now, but maybe not as intuitive as it used to be !
