Yes this is a sort of "bible" for signature campaign ... you find also impression about campaign read topic in the last pages you find a new signature already not listed (or even a new promo
)Most of the signature campaign are listed there except one or two, the OP of that thread could be busy but as you have seen on the last page you already know which campaigns are running, also you can check every signature campaign and check when were 'founded' or when the signature campaign thread was made so you can check for how long are they advertising here.
