Not trying to be mean here, but there's something you should know before posting: People here will yell at you and hit you with a stick if you use emotes too much, or in a manner that hinders the readability of your text.
Anyway, the forums here are only supposed to be used for matters pertaining to the Danbooru website (such as ways to improve it, for example), so you can't use it make threads about personal stuff or any sort of commerce.
And before anyone says it: Do not post your own art here, or else you'll be hit with an even larger stick.
That being said, welcome to Danbooru, and remember to just enjoy the site above all else :]
