How do you start your own Free company?

[DiasFlac]

After reaching level 20 Story Quests you'll be prompted to join a Grand Company.
After that you can apply to register a Free Company but you need:
3 Signatures of players who are NOT in a Free Company already
A total sum of 15k Gil

Then return to the OIC Administrator and turn the petition in and you'll be set.

Thanks but what do you mean by signatures? How does that work?

What's the difference between a Linkshell and a Free company?

In a short - LinkShell is just a dedicated chat channel.
Free company is to join the players together, level up the company and use the FC bonuses lilke Storage chest, housing (comming in future) and in general to socialize.
