I'm all for the idea of starting a new thread and splitting the old one into sections too.
Even 80 pages is a big amount and a very long time to scroll through!!
Rather than a 100 page limit maybe something more like 50 or 60. I can't see a reason why we can't have personal photograpghy vol.1, vol.2, vol.3 etc. or maybe even date them, for instance: personal photography Jan2001 - Apr2002. That way at least you know how far back in time you are going. Just a thought.
Smaller bitesize chunks. That's what I say
