“Generally, I like new replies at the bottom of a thread” – they’re certainly easier to find there instead of them getting mixed in the previous discussion. (I wanted to say missed in the mist, which must be a very common exprerssion I’ve never noticed!) I just have to remember to mention what I’m replying to.
“Did you intend attachments to be allowed ” – The little instruction box that appears when typing a comment includes something about images (<img src=…) which I couldn’t get to work. It blanked out the contents of the quotation marks (the location of the image on the web) so the image didn’t appear. Then I noticed that attachments were possible so did it that way.
