It is not a game that "saves".

when something changes, it automaticly saves to your character.

As for chatting, there are different "channels" that people talk on, especially in cites.  It is not like Diablo 2 where it didnt matter where you were. 

Terms to remember:

LFG mean "looking for group"

WTS (WTB) mean "want to sell (want to buy)"

And ask guards where things are (click on them) for general info, people do not look kindly on "noob questions".

and do wait more than one minute before reposting. 

spamming is frowned upon, both here and in WoW.

When you just push enter you are chatting in /say.  That means only people in your immediate vicinity will hear you.  Other forms of chat are

/yell, People in a much larger area can hear you.  Used to hawk wares in cities, towns, or warn people or even ask for assistance if you are in danger

/party, talk to your party members.  They and only they can hear you no matter where they are

/tell [name], sends a private message to a person.  only they can hear you no matter where they are.

/guild, talk to everyone in your guild

/raid, talk to everyone in your raid

/bg, talk to your team in a battleground

/#, talk to a person in that particular channel number.  1 is usually for general
