You need to register if you want to post on getbig. I could be mistaken but here is what I think is happening with you:
You are reading the boards (especially General Topics [this one]) and you would like to reply to certain posts and intend to "quote" the post to which you wish to reply.
You are actually hitting "report to moderator" instead. When you do this, only the moderators of this board can see your comments. The person to which you think you are responding never sees your comment and your comments do not show up on the board.
If you wish to have your comments posted on the board for all to see, you must register.
After you register, when you wish to quote someone, click on "quote" which is above their post.
If you can't figure out how to register, please hit "report to moderator" on this post and tell me what you are having difficulty with, and I will post on this thread answers to assist you.
Take care!
