Why not more pages ?

Hey guys, I've been busy as of late with new a grand daughter, work schedules, the same old, same old. A while back, I want to say before Xmas I noticed that the page count had been dropped to 3 pages. I didn't know if it was lack of posts or some type of reprogramming of the whole system. I feel that the more threads available the better but I can't seem to go beyond 3 pages. Ive put in go to 4, and nothing but the top of page 3 appears. What am I doing wrong, I miss browsing through the threads at night learning or hopefully helping someone else. I can run through 3 pages in a few minutes, so goes some of my absences. Any input would be appreciated. TY
