I am doing it. But it is too much ANN threads now. I mean the favorite one of people when saying "best"!
Nah, just make your own template. You can get redtrust even sue if using another person template without their permission. Template and all format of announcement is important to gain people interest but the more important thing is what is your ann about.
If you still want your announcement get lot attention just hire some prefessional like sylon, blockeye, or needmoney.
