Help! 

Hi Marek69. I'm in a situation of trouble...people telling me that I've broken copyright (even copying withing wikipedia). I just need to get some things straight!

 Firstly what do you have to do to attribute (I read the page, but it gave me wikipedia creep; please simplify it)?
 What do you do if you've done edits way in the past in which you've copied from other wiki articles without attribution (I only discovered it relatively recently)?
 Can you copy and paste info from other articles that you've written yourself?

Please make this clear to me. I've been blocked in the past for a misunderstanding, and I don't want to get blocked again!

Please reply as soon as possible. I need to go soon, and I hope to have a reply soon. Please reply...
