I'd be interested in helping new players. I used to play 2008-2013 and came back recently. I'm rated 750 1v1 and 1000 global so I'd be looking at helping to optimise basic build orders and help to get people into the mindset of playing aggressive 1v1.
At the moment I've got a lot of free time so if anyone's interested then get in touch and we'll find a time that suits both. I live in the UK so English language and UK afternoon/evening time.
