Okay I just started a guild called "Verdite".
If you want to join, find my sale of a gold coin in the Commission Shop for 100000000
Don't buy it obviously, but select the "Coins" until you see my name "Pyrone" as the Trader
Then select the guild in my player info and join Verdite.
I can't think of a better method of joining other than somehow finding me online.

I could help with some crafting skills, but as of right now there are no reasonable ways to get resources. You have to buy items break them down and craft them, which isn't profitable. Crafting from enemy drops is very slow, and even then the benefits of leveling crafting up don't seem all that useful.
