To receive credit for posting in the other threads, you need to, respectively:
Purchase at least one lottery ticket for the lottery (10 gold)
Enter or make a bet for the challenge (300 gold, or any multiple of 50 gold)
Buy/Sell/Bid something in the Store
Post your choice of what you want my character in my quest to do next.

After all, the point is to get the threads to be successful.

Alternatively, if you post frequently in the threads through the next week, that'll count as well- so long as it's bringing activity to the threads, the details aren't important.

That aside/
Good to have you on board! Since you were brave enough to be the first to post here (though hopefully not the only) I've sent you a gift.
