How to find an OpenSource project?

Question

open source

I want to participate in the development of some project in the format of writing a module, block, etc., perhaps fixing an error. But
1) I would like to know the one who makes the project in this issue. Vladimir correctly noted OpenSource: how do you choose projects and join it?
2) I found a bug, for example, how do I know that this is a bug and not a feature
3) Before doing something, you still need to agree on what is the point of sawing a new module if it may also be sawing it at that time, or it has in general, a different view of what it should be.
It turns out the main question is where to meet a person for an OpenSource project so as not to act separately?
