Im Back. Where do I start?

Played from Beta to 07, Quit, and finally came back.

Now I'm noticing things have entirely changed and I'm completely lost. First off. Any good social linkshells out there that might be willing to take me in?

Second: What's the etiquette nowadays? Back when I played it was Hit level 10-11 > Head to Valkrum Dunes and start up a Party. What do people do nowadays? Where do I go?

Anyone willing to help an old player returning get back into the swing of things?

Well, I'm from Ragnarok, so I can't help with the first thing, but for the second, people head over to Gusgen Mines to do what is called "Fields of Valor" on Skeleton monsters, starting at 10-15 til they reach 30, then head over to the Crawler's Nest til 60, and then Bostaunieux Oubliette til I have no clue...
Or they leech off people in Abyssea (which is usually frowned upon by the serious players)... >w>()
Leveling is super easy now-a-days.
Most people worry about getting the best armor, fighting end bosses, doing quests, getting to level 99, maxing out skills and merits, that kind of thing.
