I am new to Stack Exchange and have participated in two sites. I want to know if reputation works across Stack Exchange sites.
For example, if I have 20 reputation points in Ask Ubuntu, can I post a comment on Super User? Or should I earn reputation separately in each site of Stack Exchange to be able to use the privileges of reputed user?
Are there any specific sites in Stack Exchange that allow cross reputation?
I am signing in with my Google account. Will that affect the way reputation works?
Looking at the questions pointed out, I can see the questions themselves do not address the issue I have asked. Only the answers deal with them. So I don't think the question is duplicate, unless of course it is expected of me to read all questions about reputation before asking a new one.
Besides this question deals with a very specific issue rather than being over generalised. I think future new users will benefit from this.
