1. There is no ability to mark anything as an "accepted answer" in NNTP, let alone mark two responses as both being accepted answers... there is no way to mark anything as anything, no editing whatsoever, no up or down or accepted, no fixing speling misteaks, everything is fire and forget.

2. Yes, the ability of NNTP clients to paste the original text into a response is missing from the SQLA software. Automatically quoting text is a historical oddity from the days before modern NNTP clients let you quickly browse old messages... think of the days before copy and paste, think early email. The ability to edit quoted text builds on that... Does anyone really miss it?

I'll tell you what I don't miss: I don't miss having to scroll through hundreds of lines of copied text to get to the reply at the bottom because some people think bottom posting is a good idea. I don't miss responses growing and growing and growing in size because text is automatically copied and folks don't delete it. I don't miss having to delete the copied text when writing a response.

If for some reason there is a need to quote the original text, there are ways; e.g., paste and blockquote:

something that is usually done in NNTP by "See my remarks inline" and then quote parts of the response and then inline comments to each paragraph.

IMO I would rather have to work at quoting than have it automatic and then have to work at deleting... on NNTP, I am always deleting useless text that folks have already seen, very rarely quoting anything. I switch back and forth every day, NNTP to SQLA, and I don't miss any part of NNTP...

...well, that's not true; I miss the fact that more people are still using the newsgroups.
