1) yukko and Goldi are the same person, and she got sick of running the forum, so decided it would go out with a bang before the plug got pulled.
2) Whitesands is actually Goldi, and is confused and doesn't know what to do.
3) byeltsin is actually Goldi, and is just too excited about yukki being gay to remove the "My New Favorite Website" thread. That and he likes the link at the top of the page.
