	    <para>
		To make provisioning of user accounts convenient, 
		a web front-end to <application moreinfo="none">ser</application>,
		<application moreinfo="none">serweb</application> has been
		developed. <application moreinfo="none">serweb</application>,
		a PHP-written web application,
		allows users to apply for new <application moreinfo="none">ser</application>
		accounts, and maintain these.
		Users can manipulate their contacts, keep a phone-book
		with SIP addresses, change password, send instant SIP messages,
		and more. Administrators can manipulate any accounts and
		grant or revoke user privileges.
