I am Striker. I started contributing in the Portuguese Wiktionary, but now I try to help other projects. Even not being able to speak other language than english and portuguese well, I do an effort to help stopping vandalism on small wikis.
Important note: Since my current username is unsustainable (cannot be usurped at commons), I have given it up, renamed my account at my home wiki and am now waiting for some usurpation requests I have made under various projects. If everything goes well, I'll then rename all Striker accounts with edits to the new name. In the meantime, I'll be working on the SWMT with my current username (I'm not that active atm, but I'll restore my full activity when I finally get this procedure done xD). Thank you for your attention.
