Hello, New to DP,Have a few questions please

I just joined DP yesterday, however there is a few things I don't really comprehend. Would anyone be so kind to help me with those questions, actually I only have two. It's about the itrader thing, I was on the buy and sell forum looking around and I notice a lot of talk about itrader, I know it's something with a rank or reputation. But how do you get it? Also is it possible to change your username, cause I find this a really stupid username, but it was rather late and I didn't feel like spending time thinking of a username to fill out email and dp registeration .So I just wrote the first thing that came to my mind. I find it rather foolish now.
Thanks /

 

1,About iTrader you can get some info from here
2, You can not change ur username

 

Thanks, that was a very compresensive thread, however I'm slightly confused, I thought I saw on a sticky in the forum that you couldn't ask for itrader?
Also is there a different between rep or itrader? cause the person asked for rep, but that wasn't a buy/sell/trade forum? so how would you give Itrader or rep for those?

 

Rep is different from itrader. Itrader is how you do it buy trade and sell. Rep is how nice you are.

Yup.Asking for, or offering, reputation, is not allowed. you can get some info About rep from here
