well, recently I've tried these three tools, and now I'm here to share my expericence with you guys. xrumer->powerful. I haven't buy it, but all people said that. but, it's too expensive. senuke-> I don't know why, but the programme never works, whether I use it to signup or post. prstorm-> Sucks. Is there any other tools anyone here want to share with me? otherwise I will just go buy xrumer some time later.
