Displaying key information at the top might work well for some major threads, for example making this image of the new kit a sticky post at the top of every page in the "New Kits" thread?
Before this goes off topic, please keep kit discussion in the thread in the main forum. when I first read your post Nath I though WTF and then I realised you were referring to posts rather than threads. Actually having Sticky posts is a damn good idea. I don't think it's possible with the standard software but there might be an add on.
If it isn't possible, then surely a gentle reminder to those who post the first post in a page. If that doesn't work and a mod has the time they could always edit the post themselves, although I appreciate that's time consuming, however how many key information threads will we have?
Could definitely be handy for some threads, always keeping the key information/links etc. at the top of the page.
Whilst a good idea, this isn't really feasible as you can select how many posts appear per page in your own settings.
