Clan suggestions:

Recruiting:
Make a good forums post that gets bumped atleast once a day.
Let council and above help with making it. It can be a lot of work.

Rules:
Reqs: Fcape, Piety and barrows gloves for a rank.
No Multi-Clanning (Not counting Skilling/Social/PvM clans).
No luring/scamming even if outside the clan to random people.
Don't crash clan members.
Don't flame clan members, banter is okay. Discussions can me taken in PM.

Ranking:
Set clear requirements for the different ranks.
For an example: Smiley if you are a social that doesnt fit reqs.
Joining and meeting reqs = 1 banana.
20mil+ Shared along with 1 month spent in cc = 2 bananas
50mil+ shared along with 3 months spent in c = 3 bananas
100mil+ shared along with 6 months spent in c = Bronze Star
Council = Silver
Leader = Gold
THESE ARE EXAMPLES.

MOST IMPORTANT:
Make a clan account that hosts the CC. F2P accs can rank 200 members, P2P needed for 200-400.
If P2P is needed. Let gold stars pay with bonds (should be like 1mil each every month, nothing at all)
Give all gold stars access to the account.
Let gold stars rank people.

It helps a lot so that not only one person is ranking and it doesnt put all the burden on one person.
