    I am unsure how to restore a user with the user.settings.USER_DELETED or restore a USER_INACTIVE any help would be appreciated


    My doctor said I have the body of a 25 year old ... and the mind of a 10 :-/

    USER_DELETED and USER_INACTIVE are bit flags. An integer can hold many bit flags (typically, 32). In the case of user.settings, each bit as a pre-defined purpose and those bits have been assigned symbolic names (in userdefs.js).

    To set (add) a bit-flag, you bit-wise "OR" it into the value, like so:

    user.settings |= USER_DELETED;

    To unset (remove) a bit-flag, you bit-wise "AND" it with the opposite (bit-wise not) value, like so:

    user.settings &= ~USER_DELETED;

    Hope that helps,

    interesting ... that &=~ ... undeletes? no wonder USER_DELETED = 0 didn't work ... thought it was a BOOLEAN o.o

    It unsets a bit (or a set of bits). In this example, it's unsetting the "USER_DELETED" bit.

    no wonder USER_DELETED = 0 didn't
    work ... thought it was a BOOLEAN o.o

    Nope. jsobjs.html is you friend. :-)

    user.settings &=~ USER_DELETED;

    as learning any language ( obviously I am not C adept) what does ~& or even just ~ mean negate a bitwise?

    https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators

    '~a' inverts the bits of 'a'

    'a & b' returns ones in positions where both 'a' and 'b' have ones

    'a & ~b' returns ones in positions where both 'a' and the inverse of 'b' have ones

    'a &= b' assigns the result of 'a & b' to 'a'

    'a &= ~b' assigns the result of 'a & ~b' to 'a'

    'a | b' returns ones where either 'a' or 'b' have ones

    'a |= b' assigns the result of 'a | b' to 'a'

    So:

    var a = 1; // 00000001
    var b = 2; // 00000010
    a |= b; // a = 00000001 | 00000010
    a &= ~b; // a = 00000011 & 11111101

    if that makes sense.
