Hi,
IRo is Ragnarok Online Official Server which is based in US, There's no IP region block or registration limitation here (such as KSSN number prerequisite applied in KRo)
The official language pretty much is english, but you can use your native language if you knew your chat counterpart understand you.
You can find various people from various countries playing iRO, you can check this subforum for foreign language discussion.
You can earn zeny from various sources as starter.
See my first post on this thread for reference to early earning zeny.
If you want to earn zeny from miscellaneous things such as (maneater blossoms, stems, witched starsand, etc) you can read this page. You can learn which monsters dropped the materials by clicking on each items you wished to know.
I suggest you to collect acid bottle, bottle grenade and potions derivatives ingredients if you wish to earn zeny from miscellaneous loots or you can also made them and sell the finish goods instead by build yourself a brewer alchemist or biochemist class.
Hope this helps.
