The FC and linkshell systems need several additions to improve the entire social atmosphere of the game, such as:

1. FREE COMPANY ALLIANCES
2. FC challenge logs
3. FC calendars
4. FC bulletin boards
5. FC achievements
6. Ability to sell or return FC houses
7. FC merger system (combines points/assets)
8. Linkshell messages
9. Linkshell bulletin boards
10. Linkshell calendars

That would be a good start.
