I did not receive additional privileges per "Join Meta today and earn extra privileges like posting, commenting and voting." This message shows up if you (for example) try to comment without an account.
I believe this may be because I used my previously existing SO login, so FYI you appear to be unintentionally penalizing new Meta users for having a previous SO login.
.. Moderator so to accomplish ".. earn extra privileges like posting, commenting and voting." as promised - I believe you should kindly credit this StackId account at least 5 reputation please.
