I am Brazilian, and my home account is at pt:wiki.
Before accounts unification, I moved my username from pt:user:Sonlui to pt:user:Yanguas at pt:wiki, but here, in en:wiki, I kept username Sonlui.
Then unification came and created user:Yanguas. That's the one I've been using. If you want to talk to me, please message at english talk or at portuguese talk.
Thanks.
