I don't think I'm explaining myself very well.
I am always logged in... my browser is set that way.
But how can a post that is UNREAD, (on a thread that I have been involved in) be UNREAD in the MY list ... but not in the total list?
The best option is
'show unread posts since my last visit' That will always show
every unread post since your last visit
AND when you last clicked
"Mark all messages as read'. The other option will show actual posts in response to your posts, but not the
most recent post in any topic which has seen posting since you last invoked
'show unread posts since my last visit'.
In summary, if you want to see the latest post in every topic that has had any posting in since you last invoked that option, use
'show unread posts since my last visit'. If, however, you only want to see actual replies to your posts, but not necessarily the most recent post in a topic, then use '
'show new replies to my posts'.
While we're on this subject, we probably need to be clearer about terminology. There is one forum (Three Towns), three Categories (Forum central, The Local, Members' lounge) nineteen Boards (the different sections within each Category) and a whole welter of topics.
This topic
"Suggestions, problems and queries" contains various
Threads; more than most, actually, since it's all about different questions, but this apparent rambling of mine has a point.
'show new replies to my posts' is more
thread oriented, while
'show unread posts since my last visit' works on a
topic by topic basis.
