Land Before Time meets Wikipedia:
One day, a time traveling editor/LBT fan jumps to the past with an "ethernet cable to the Future" to get first person facts for the LBT character pages, to establish notability before the pages are deleted. But the jump gives him 365 million years worth of carpal tunnel, so the gang has to figure out not only what a computer is, but how to use one and save their Wikipedia pages from being deleted!
In the end they fail and the pages get deleted anyway (as any Wikipedian from 2008 would know), but they learn that there are more important things in life than having a page on a website that doesn't exist yet and will never effect their lives in any way.
