Notes
• In effect, the perms for articles published on this Wiki are PERM_COPY and PERM_TRANSFER until you log in, then PERM_MODIFY, PERM_MOVE, PERM_COPY and PERM_TRANSFER.
• The perms of a newly created script are: Base = PERM_ALL, Owner = PERM_ALL, Next = PERM_MOVE or PERM_TRANSFER, Group = 0 (none), Everyone = 0 (none). These perms are the same, no matter if the script is created in user inventory or in an object.
