Hey there, and welcome to the community! A very simple answer on how to build up your rank is to be active, publishing reviews and being a part of the community.
Kindred has a great thread about tips everybody should know
about Eden, and Viktor wrote the student's guide to the mentor program
. There's also a whole bunch of super friendly people willing to answer questions if you ask them, whether it be through a personal message or here in the forums. Just be sure to do a forum search before you post a question though, a lot of times it's been covered a few times already and people who have given great answers in the past may not always want to repeat themselves. Also, I've had some questions answered very thoroughly just by searching.
No matter what though, welcome to the community!
