Months ago I began to visit this site much less often out of frustration. On those rare occasions when I tried to post, posts were often blocked because I was told that I wasn't logged in (when I patently was) or that I needed to have permission to post. There was a thread here about the problem but it's now closed because the problem was 'sorted'. I'd not looked at the site for weeks, finally did so this evening, and tried to post: The problem is not sorted. Not logged in, haven't permission, same old same old. If the problem can't be cured, it would be very nice if someone trying to post could get this message as soon as the box for the post showed on screen, rather than after some thought had been put into composing a post. Thanks for any help you can give.
