Where have the old threads gone?

[childe]

Sorry for being off topic, but I can't figure out how to view any more than the 46 threads that I am currently being presented with. I know I used to be able to do this, but its a long time since I needed to and now can't remember how or figure out how to do it. Sorry for being thick, but would someone please help?
Thanks
