Best way to manage the clan organization is to split it in cps (constant parties)
After you are done with this, every party has its own goal regarding leveling, gearing.
Eventualy this is how a clan works.
Clan should have events to help people gear up, lvl up. This events could be raids, epic raids, olympiads, pvp event, devil isle night farm, hekaton.
If clans cps are low on lvls, then you should focus on raids, exp, to join devils isle / giants cave
Making a clan wh to feel up clans needs is a must. But clans members should be Also rewarded for their time invested.
clan discord / fb / Viber or I don’t know is must for chatting and notify people. Ts is more important though.
