Quick Definition: This original, and now spam-filled, newsgroup formerly known as ASF.
uASF is the term that PUAs use to refer to the newsgroup alt.seduction.fast, which was one of the first online forums created for the seduction community. The forum eventually became overtaken by flamers and spammers, and the archives of ASF were transferred to a new forum known as moderated ASF, which can be found on the Fast Seduction website. The old ASF archive is now referred to as uASF to differentiate it from the newer mASF.
