I just find out that I have been banned by the v7n admin. What does it mean by SPAMMING WEBMASTER FORUM? I am new to V7N and just post two introductions and one thread (unsuccessfully). And one hour later, I am banned.

Can anyone tell me why? How to define Spamming forum?

well, what post you made about? (the unsuccessfully one thread?)

Yea, my mind straightly tells that you did wrong there, you can't post an introductory thread twice. Okay, spamming is....uh oh where's my glasses..
