I see, thanks. I just want to prevent anybody from deleting the symbolic link. From what I understand then I cannot change the permission of this link without the help the administrator, correct?

Not even with the administrator's help. File deletion depends on the permissions of the containing directory, not on those of the file. (rm specifically checks the file for read-only unless you pass -f, because one usually doesn't intend a read-only file to be deleted, but unlink() doesn't care. Try it from Perl or Python sometime.)
