What does it mean here: http://stackoverflow.com/privileges/participate-in-meta when it says your reputation on meta is the same as your reputation on the main site because in my experience this is not the case. Can some explain this to me or is it an error in the documentation?
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
Not an error. Meta Stack Overflow is run as a fully fledge site, and is the Meta for both Stack Exchange and Stack Overflow. All other per site meta, ie. Meta Super User, is linked to the main site and user accounts are synchronised between the two. All sites have their own meta's, apart from Meta Stack Overflow.
This is true for all "child" metas in the network except for Stack Overflow and Meta Stack Overflow.
Meta Stack Overflow server as both the meta for Stack Overflow, but also as the Meta for the entire network. Due to this, it is not considered a "child" meta and its reputation is independent.
