Hi guys! I am new to the markets. I have had my retainers for quite some time but I am finally taking some time to learn the system and making some money! (Ok I only make about 30,000 -50,000gil a day which I am sure is chump change to most of you)

I am getting addicted to the whole supply and demand process but I have a few (very n00b) questions:

1. What is a RMT? I keep seeing that thrown around on these forums.

2. Is it ethical to buy [Item A] from here [NPC] and sell it at a higher price than what you bought it for?

3. Any specific items that are ALWAYS in demand?

4. Does it matter which [city] market you sell in?

5. If you are on Coeurl server and you have been on another server, how would you say our economy compares overall?

6. Any other general tips? I am only level 40 so I cannot sell super rare end game stuff...yet.

Thanks!
