Now this account joined this site(meta), but when I move to Stackexchange.com, the page asks me to join the community, is it normal? if so, is it also apply to other sites?
(I remember this account joined the community from meta.stackexchange.com, but not from Stackexchange.com, now I visit stackexchange.com and still ask me to join the community, as if main and meta are different sites)
(I test again: login to meta.stackexchange.com with google successfully, then move to Stackexchange.com, but in Stackexchange.com I'm not logged in. When I login to Stackexchange.com again the site asks me to join the community, sorry I dun know how to capture screen and can only describe the story with words!)
