I'm new here, so please don't take offense to this suggestion, not meaning any harm just an observation....
I have many hobbies, pinball being the newest and the most enjoyable yet. I spend much of my time online learning whatever I can about my hobbies and tackling projects on my own.
This is a great site for pinball hobby! One thing that may be very useful to many would be a how to section that is broken down into different categories from restoration work to repairs. How to's that include step by step and photos as you go would be great.
Sure, I can dig some of this info up on the web... but why not right here at Pinside?
Read a post yesterday about someone needing instruction on flipper rebuilds... Great task for a how to!
One site I visit for my truck has a certain format for the how to's and they are submited for approval of a mod to ensure that they are quality posts.
Just a thought... Not trying to step on anyone's toes.
