The Email account linked to this blog has a 10 Mb capacity which is fine most of the time - as long as I remember to clean it out periodically.
I haven't been active online very much over this winter, so the Email filled to capacity without me noticing. I only realised something was wrong when I logged in and saw a comment which Blogger hadn't notified me about.
So if you've sent me an Email and it bounced, or left a comment and you think I'm ignoring you, it's all down to a full mailbox and me being far too lax about clearing it.
Sorry about that.
