Abstract: A method of sharing access operations of at least one bookmark node with an associated access level for each access operations by at least two identified web users. The method includes steps of allowing performance and barring performance of the access operation by an identified web user of the bookmark node. The access operations including viewing and editing the bookmark node by an identified web user. Whenever the associated access level of a first access operation allows an identified web user to perform the access operation upon the bookmark node, the first access operation of first bookmark node by first identified web user is allowed. Whenever the associated access level of the access operation bars the identified web user from performing the first access operation upon the first bookmark node the performance is barred. Other embodiments of the invention are computer programs on computer readable media.
