Well Steemit may not be the best medium to do this...
(tempted to direct you to look me up on LinkedIn and start InMail correspondence for the no-strings attached pointers)
However if you feel that it 'could' work then I suppose we could do it here under a learnenglish tag or somesuch.
The English language is a victim of its richness and flexibility. It is not the easiest language to master but we could make it fun.
How do you feel about roleplaying online? I can make language learning an active element of that (and it ties in to my theories on how learning should be fun at all ages).
I am open to suggestions. :c)
