The amount of tings you have to take into account as a tutor nowadays is staggering, and a huge minefield (I'm currently starting CTLLS). Worse still, my main area is ICT (which includes stuff such as this) so we have to be extra careful - although it doesn't involve tutoring schoolkids!



Bottom line is, a laughs a laugh, and if you're happy to perform in front of a cclass, then really youtube isn't much more - you can get the derogatory comments in school as well as the website!
