Yeah. What you describe is what I have now. That is way too inefficient for my tastes.
What I want is to use the
RSS feed to check for new threads, subscribe to those I find of interest, be notified of new postings to subscribed threads, and then go directly to the first non-read posting in the subscribed thread. (This is what I had up to last Thursday or Friday.) No muss, no fuss... quickly done.
What I have now is Browsing to the ER Forum, clicking on UserCP, clicking, in turn, on each subscribed thread with new postings, paging down through all the posts until I no longer recognize one as having been read, and then reading the new postings. A long boring affair.
