[QUOTE=Duncton;420388 For example, searching for a specific formation (eg. 4-1-4-1) doesn't yield any results. But it's not easy to phrase the right question anyway.[/QUOTE]

1) A tag function could improve finding formation-specific content
2) A lot of formation discussion is very dated, cleaning up the stickies and updating content would help.
