Wikipedian since mid 2008, year-long active Wikipedian (I used IPs when I went out in vacation) since early 2011.

You never heard about me? Eh, it's Guilherme, Sagittarius 1994er, carioca (Brazilian from Rio de Janeiro), en-2 and es-2 user.

Mostly active on the English Wikipedia (link to my userpage there) since late 2010.
