On Gjallar :

I try to do

self newUser: 'toto'.

with an admin consol and I obtain

MessageNotUnderstood: ByteString>>canRead:'

I've tried to debug it but I have to understand your event mechanism and 
  its seems to be hard for me at the moment...

I want to add a simple user to my gjallar application....

May be I've not understand something?

thanks for your help!
