Much times I can see exists some usefull posts in stackoverflow and meta which are not questions, are posts to show something to the people, for example little tutorials or something similar, sorry I don't have any url to show you, but sure someone know what I'm talking about.
I have more than 400 snippets from mine which are usefull and generic functions, reusable code, for VB.NET languaje.
My question is if in any part of stackexchange sites I can share my little knowledges (instead of asking) by sharing my collection of functions and to learn points? I/You can post something that is not a question on StackOverflow? or maybe that extended posts of tutorials are only from moderators and staff and the rest of the people only can post questions?
