Three take-aways (important key ideas) that you've learned from the two netiquette websites. 

1. always check the end of the website (whether is .org / .com / .gov) 2. check the author! are they credible? 3. when was it it published? this gives you a big clue whether the information is still up to date.

this should be correct, if you have any other questions comment them and i’ll try my best to help! :)

Apostrophe and allusion. because an allusion is the way of writing about something, yet not explaining it in vivid detail.

See is the english verb.
