Hi Doreen L = List mode , all posts to the list will come to you individually Its then easy to read each and delete those you are not interested in D = Digest , posts will be accumulated either until a certain size of posts is reached or a period expires, you will then receive them all in one go in a digest Personally I can't abide digests as they cause so much more work (like the need to change the subject line like this post :-) should you want to reply to a post in one but it is a personal choice These days you are highly unlikely to be inundated by posts no matter which lists you subscribe to Nivard Ovington in Cornwall (UK) > Dear Cara, > What is L mode or Digest mode? > > > RegardsDoreen Ross
