Done voting and supporting @arcange as a witness week before I got in steemit a friend who invite me here ask me too and no regret by doing so even though that time don't know much what witnesses does in here.. I like they way how he sends warnings on scammers,phishing and hackers.. very useful!! The alert thing is a very big help and the statistics report is an informative. Don't know much of his works as witness but doing those I mention is already a lot.
