Yakin nggak ada Indonesian Slang?
Aq di KasKus cukup aktif di sub-forum English lho, & dari sana aq baru tahu kalo' frase "thanks before" itu nggak ada dalam Bahasa Inggris, itu cuma terjemahan harafiah dari "terima kasih sebelumnya". Kalo' yg bahasa Inggris asli adanya "thanks in advance".

wew? cukup menarik juga...
boleh kasih link forumnya?
