# Capabilities Classes

The 'caps' column in the 'user' table is a 16 bit mask with a bit on for each capability class the user is a part of. Each site can define their own capability classes in `cgi-bin/ljconfig.pl`. Then, each capability class can define its own limits for the following things. The `LJ::get_cap()` and `LJ::get_cap_min()` functions will consider the limits of all the classes the member is a part of and return the max or min limit, depending on what it's being used for in the code.
