I wish I could video online but it unfortunately not effective for me as a deaf/blind individual. As signing in person with someone. Given that I cannot view contents (and thus signs) unless I am right up on the screen comprising my abilities to effective use it for obvious reasons.
So I either use services like IP Relay Service, emails, google hangout (or anything similar) depending what type of person I am talking to and/or avenues available to them (like businesses sometimes only having phone lines so obvious I can only use the relay with them).
