stoot has said that the Christmas Yeti and the Chocolate Easter Egg (the Easter egg trophy) will go with you to the next version.
And back to the original question, everything gets wiped except:
• your avatar/customizations/owned clothes
• your credits balance
• your name
• your profile (anything you've filled out)
• your friends list
• a few custom/special items (yeti and bunny, so far)
Artilect, not sure what you start with. It's been a long time, personally, and it may have changed (and may still change). 100 currants? I know you get a hoe. And access to butterfly lotion. Not a whole lot.
I think you're given 100 currants once you leave the start street, and your bag will contain a small amount of food (sandwiches and/or crudites, I think).
During the tutorial, you can choose to pick up a seasoned bean.
On the start street, there's a musicblock, butterfly lotion, five spinach, and five fruity drinks. You can pick up all of these, if you wish.
If you choose to be greeted, you may or may not be given beans, lotion, spinach, drinks, musicblocks, awesome stew, cosmapolitans, or gameshow tickets. Greeters can distribute these items at their own discretion.
At some point during the last test (my first!), I know it was at least a couple days in.. I suddenly had a small bag with the name Newbie that was filled with 250 each for grains and meat, and 80 butterfly milk. I believe it also had some drinks and a couple of other things. I searched my log area and found nothing saying that someone had given it to me, or maybe I just completely missed it. I thought at the time that the system issued it, but now I wonder if I was wrong about that.
During the last reset we all had to go through the tutorial again. I believe you get a hoe,warering can, 3 cherries, a Lemburger, 6 beans, a meat, 8 common crudites, 6 fruity juice, 3 cloud 11 smoothies, 1 butterfly lotion, 1 butterfly milk, 5 spinach, 1 random music block.
@glum: I think you must be right! It happened when I was still trying to figure things out so I feel badly that I was not properly appreciative. I've learned so much more about Glitch so far and have fallen in love with it. These forums have been a great help with that as well - the game is currently closed and I'm still learning so much! The incident with the lovely stocked bag has inspired me to attempt to do the same thing for others.. it was such a great gift and helped me so much.
To add something on-topic :) I think I also received sammiches during the tutorial or sometime around it.
