After asking a question on EE forum concerning an aspect of my home project, I figure out that some peoples were interested by what I am planning to do. And maybe those people want to follow the project, to see how it grows.
So I thought that it may be a good idea to create a kind of new feature where people could deposit some file, introduce the project, explain what they are doing and why. Other people could ask the project owner about a specific part of the code, schematic, or overall system.
It doesn't look like anything existing on stack exchange so I'm pretty sure that won't be possible.. But still, I think it's a good idea :)
