Yes this certainly can be a challenge. As I think most members here on PC know, I primarily reply to posts by new members. And it's not unusual for these to be walls of text. Sometimes the moderators will go through & break the text up into paragraphs (which is greatly appreciated!) But not always. I simply do the best I can with the ones that are left as they were written. There have been at least one or two though I can recall that were so long I ended up skimming parts of the post. I don't like to do that. But there is a limit.
