What is this prefix '~' thing? I saw it describe ages ago, and the local guru claimed I misunderstood it. Can't find it on Google. > d. the url includes a <prefix>FieldName, such as > http://www.example.com/~FieldA/Group/Page > (prefix='~') > http://www.example.com/wikifarm/FieldA/index.php?n=Group.Page > (prefix='wikifarm/')
