For a customer of mine I am looking for a Clan Management System for his Clan site.

He would like the following features:
Clan Managment system
- members could create a clan
- members could join an existing clan
- members could view other members in the clan
- two clans per member (has a prevention)
- clan profile
Match System
- Sumbit a ticket to another clan for aproval of match
Match finder
- Members could find and create matches
- members could
Clan Ladder
- a ladder who won the most matches and has the least lost
- possibility to view ladder

Is there one of more XOOPS modules available which could do this? I'm fairly new to XOOPS so I'm not too familiar with the possibilities.

Linux-gamers.net uses my Team Module - but that is just for individual clan sites and not a ladder module for a competition site.

Mithrandir's team module is actually the only available module related to clan activities.

I don't think there is such module you are looking for. The only solution I can see at first sight, is to play with group permissions. For each and every clan, create a dedicated group, with specific access. Then some modules allow to display content regarding groups access...

Of course, groups creation and member enlistment must be operated with admin agreement...
