user add new
Only project leaders and managers can add new colleagues.
Your 
colleagues
differ from project to project, so what you put in this form only
applies to the 
project
you are working in.
 
Using the appropriate tab, you can
- provide the name and email
address of a single new colleague,
 
- use a list of colleagues to add
in a relatively free-form list so that you can easily copy and paste
from other sources, or
 
- make the project available to anyone who knows a special link for 
it (see below)
 
An email address uniquely identifies someone;
their name is helpful to other colleagues.
All colleagues added at one go are assigned the same 
rôle, though you
can change them immediately afterwards using the  form.
 
Who can do what?
Consult the list of 
who can do what.
How do I remove a colleague or promote or demote them?
Use the 
form. Click the pencil icon and either choose the new rôle or
(remove) at the end of the menu to remove them.
Making a project available to anyone
If you tick the box to 'allow anyone who follows a link to the
project folder to participate' in the 'anyone' tab you will be provided with a URL which
you can circulate by email or publish on a web page or blog
etc. People still have to 
log in and 
identify themselves, but you do not have
to add each person explicitly to the project.
 
You can also add users explicitly to such projects. This is useful
if you want to send an invitation, which doesn't then require them to
log in.
