Do people post same discussions again and again?

Yes I have seen them. We are to search the topic on here first before we post so this doesn't happen. However many newbies don't read the guidelines and there for will post the same thing over and over again. Or someone in a hurry to make a million on here, will see a topic that is doing great (a newbie again) and will post a discussion like it, thinking we get paid per response. If they get reported, mylot will delete them.

Yes.I'm always seen mylot members posted the same discussion at the same time! Most of that kind of discussion is come from our new comer members!

I think sometimes there are a lot of the same discussions up and I think the main reason is it takes too long to search for a certain discussion, since people are very impatient sometimes, they just go ahead and put up that discussion, and they may or may not know that it is already up just because it is just inconvenient for them to find out before posting it.

I must admit I did this myself recently. I was ready to start a blog (something I had never done before) and I posted the question both to the writing forum and to the reading forum (my blog is on reviewing books). I was surprised that the answers I got were from totally different people and even different answers. It was useful to have it under two different headings. Now, normally I would not do this, but I really did get some value from the discussions. Just trying to help you understand why someone might do that.
