SIEFReach网站已于2008年8月21日正式开通。下面的摘自网站：
https://www.siefreach.com
SIEFreach offers Legal Entities to be grouped in order for your company to be flexible regarding administrative activities for managing SIEFs. The first step is to create the Legal Entity Group(s) and have the Legal Entity Group Administrator (LEGA) subscribed to the system.
The first person for a group of Legal Entities to subscribe to the SIEFreach system is the LEGA, who will complete a form with personal details, as well as the Legal Entity Group details and Invoicing details.
我不是很理解文章里提到的LEGA？专家可否解答一下！什么样的人有资格成为LEGA？成为LEGA有什么责任和义务？
