It seems as though I can only log in and post under New Reman, which makes it difficult to RP as my other two countries Romulii and Fourth Internationale. Could anyone help me out with this, please? I created the other two simply to RP from a different perspective while not damaging New Reman's reputation.
Both nations need to have their email addresses validated. There were some problems with that over the last month or two, so I've popped out a couple of new email validations to your listed email address. Be sure to check your spam folder.
BTW, the best way to report this is via the Getting Help page (see my sig).
