@Martin saidIn fact I miss the option to replace paragraphs by [...] as I did in earlier times. Now I just have to delete everything I am not replying to.
I have just replied to a post and was able to amend the bit quoted that I was replying / responding too.
In my case it was innocent; I was simply aiming to show the point I was replying to.
But surely; if you can amend the post you are replying to then this is wrong and open to abuse.
My suggestion is to remove all cuts by "[...]" to show where the quoting poster removed words.
