Okay, so this is a really simple idea that I don't think needs a lot of explaining.
Possibility of a "thread" NPC, possibly called 'Fred'?
What Fred does is open an interface in game that has links to guides, one section for iron man, one section for normal guides, one section for mini-game guides, one section for boss guides and one section for miscellaneous in game guides
So under "Normal Guides" you'll be able to click on something like 'Runecrafting guide by F 8 - 2512' This will take you to his runecrafting guide.
The idea for this is because Im always seeing people posting asking for thread numbers. I feel like this will stop the hassle of people asking and will increase productivity.
Edit:
Someone pointed out that some players would be just too damn lazy, theres also the fact that some players might not find the thread theyre looking for on the ingame repository.
For this i suggest that there may be a "custom" tab where you add your own thread ID's.
