Some, but not all, of my Gadgets reputation got migrated to the Android SE along with my questions and answers. I speculated that this is because I got upvotes on Gadgets from users that don't have accounts on Android: correct?My mistake: I had an upvoted and accepted answer from Gadgets that was re-upvoted and re-accepted by the OP shortly after its migration to Android.
Not all of my Android-related posts were migrated to the Android SE. My highest-voted answer was to a question with (I see now) only an "iphone" tag, so it got migrated to the Apple SE (where I don't have an account). Is flagging for moderator attention appropriate in this case?
gadgets.stackexchange.com redirects to the proposal page on Area 51. Is there a way to access the site, or do we have to wait for the data dump to become available?
Do migrated posts count towards commitment on the Android SE?
Reputation is not migrated between sites.
Yes, flag any post that was not migrated and we'll address them. I have migrated the one you mentioned.
