Hack hack hack... . Implemented security assertion idea punted to mailing list (pretty easy to back out if someone comes up with a better idea) so editing "my details" works again. Rationalised and cleaned up the actions in any case. . fixed some more display issues (stuff appearing when it should and shouldn't) . trying a nicer colouring scheme for the top level page . handle no grouping being specified . fixed journaltag so the logged-in user is journalled, not admin!
