Bill, neubrain's method has worked fine for me, so I suggest you give that a shot.
Many thanks. That did the job.
What if you are the last person to post in that topic and you just want to see if something new is there?
Indeed. The Stylegala.com forum is a modded version of phpBB from which the owner removed the last post author info during some remodelling a while back.
Without that info, I found the 'new posts' page (typically my bookmarked entry page for the forums I visit) was less informative and consequently less useful. So much so that I requested that the admin reinstate it.
They never did, and they've since sold the site (w/ forum). Given that the new owner promptly screwed up by deleting the majority of the user list db entries (thereby requiring many long-standing members to reregister as new members, I don't imagine that reinstating the last post author info is high up on the list of priorities.
Like I say, it's hard to quantify how much you use it to get an impression of forum activity, but I found that I made more 'use' of it than I realised.
