Best guides are in that section there (the rules)
- Abide by the community's rules
- Have a good and helpful attitude, voluntarily help newbies
- Try to be active in game and on the forum (of course not everyone can be active)
- Don't ask/hint for it.
If the helper applications are open (which I doubt they won't be for a while) then you can apply there.
