This core element (Main's 10th) allows you to manage your bot Members and some values for the Roster. It offers several settings :
AutoInviteGroup: Which user group(s) should be automatically marked for autoinvite if AutoInvite is set to On?
Mark_notify: Are members or guests automatically put on notify?
MembersUrl: What is HTTP(s) Members interface URL (FC official by default, or your prefered mirror) ?
Notify_level: Are only members (2) or guests too (1) automatically put on notify if Mark_notify is true?
QuietUpdate: Do roster update quietly without spamming the guild channel?
Roster: What should we use to look up organization information? (Fallback means that if XML fails the cache will be used)
Update: Should the roster be updated automaticly?
It has a linked module described here http://wiki.bebot.link/index.php/Roster.php
