Capabilities are used to define limits that are imposed on user accounts. For more information, please read Chapter 21: Capabilities Classes.
Consult Section 3: Capabilities Reference for reference when defining capabilities.
No matter what your setup is, %LJ::CAP_DEF should always be defined, set with sane limits per capability.
Example 9.2. Sample %LJ::CAP_DEF
%CAP_DEF = ( 'maxfriends' => 5, 'userpics' => 1, 'checkfriends_interval' => 60, 'checkfriends' => 1, 'styles' => 0, 'todomax' => 25, 'todosec' => 0, 'friendsviewupdate' => 30, 'findsim' => 1, );
Classes. Classes are defined as hashes under the single hash %LJ::CAP. The keys of %LJ::CAP are the 16 different bits (0-15). The keys of those hashrefs are the capability names, and the values are the capability settings.
Example 9.3. Sample %LJ::CAP
%CAP = ( '0' => { # 0x01 '_name' => 'new user', 'userpics' => 1, }, '1' => { # 0x02 '_name' => 'free user', 'userpics' => 3, }, '2' => { # 0x04 '_name' => 'paid user', 'styles' => 1, 'makepoll' => 1, 'userpics' => 10, 'paid' => 1, 'useremail' => 1, 'textmessaging' => 1, }, '3' => { # 0x08 '_name' => 'permanent account', 'paid' => 1, 'useremail' => 1, }, );
