You can try the following:
- Start by screen capturing something important. (enum result? anything trigger ur next step?)
- Left a message in the forums says “I am willing to help for this box/challenge”
- Friends will ask u some boxes u solved >1 month ago
- Yes, you will forget the detail of that box
- Use the screen capture to recall ur memory and help them
You will start to capture/write down sth everyone asking/ critical point in ur notes. You will also write it in an organized way if u will read it again.
I hope it helps.
