Hi, I'm new to SEBLOD and I find it really amazing. I'm currently working on my office app to record all received and sent official mail to an online system / record, I have a few problems that I need help:

1. Since everyone registered and using to record their own mail, how can I restrict the user to only display their own list of data and modify them accordingly from the 'Lists & Search' function? 

2. While each of the user restricted on their own records, the administrator / super user have the full access to all of the data submitted and ability to modify the accordingly.

I do really appreciate your help and may this also help others.
