Also, you can make points in auctions offering anything (chat, thumbing, emailed doodles) or nothing (donations), meet people on express and make points at the same time.

here is someone's exlpanation, hope it would help:
If you write comments ppl can give you points by clicking the thumbs beside them. You can write a bunch here, or in herds, or on express, then go thumb other ppl and they will RTF=return the favor

my dear pet, thnx coming to see me... you could gain some points first, then you can buy some pets that you like
