Here are a few guidelines for you guys to follow if you aspire to one day obtain a promotion to Higher/Elite Guardian.

These ranks are given to members when they have proved they can be role models for their clanmates.
What does that mean? A bunch of small little things, but also a few big words.
On the forums:-Greet new members
-Make High Quality Posts of a certain Length
-Be Helpful
-Positive attitude (no negativity)
On IRC:-Say hello to people who enter
-Don't spam, repeat lines too much
-Spamming event notifications when they are approaching
-Be Helpful
-Avoid flaming, provocation
On RuneScape:-Attend Events as frequently as possible.
-Add other WG members and speak to them
-Train combat skills
-Coming to another member if he needs help
On RSC/Public Forums:-Display a positive image of WG
-Follow that forum's rules
-You represent WG, so don't flame/bait
-Attempt to recruit members to the clan
Overall:Be helpful, enthusiastic, mature,
active, polite, don't suck up, strive to be as good a member as you can. Participation remains very important.
Of course, you need to have been in the clan a for a certain period of time, to prove your loyalty.
Good luck!
