about the ann thread . the ann thread suppose to be created first before a bounty starts , that is what i observed on other projects .
Even if you didn't create any ANN thread, that's fine. That's just how people usually did it, but doesn't it's the only way.
Even some projects don't create any thread here at all. Exposure is what you're looking for. If making a new thread does not increase your exposure then it's not that useful.
