I am a member of the "italki Language Moderators Team" as their english language moderator. I will be more than happy to answer any questions you may have pertaining to the english language.
Please contact me by mail if you want to invite me as your friend. My reason for this is because of the conflicting problem of time zones. Please compare your time zone with my time zone (GMT -05:00) eastern.
I don't want anyone frustrated or disappointed because they can't contact me or be online at the same time as me.
