Every kind of activity can be asynchronous:

A big difference with TCP sockets or MPI communications is that
communications do not start right away after a
-:cpp:func:`Mailbox::put() <simgrid::s4u::Mailbox::put()>`, but wait
-for the corresponding :cpp:func:`Mailbox::get() <simgrid::s4u::Mailbox::get()>`.
+:cpp:func:`Mailbox::put() <simgrid::s4u::Mailbox::put>`, but wait
+for the corresponding :cpp:func:`Mailbox::get() <simgrid::s4u::Mailbox::get>`.
You can change this by :ref:`declaring a receiving actor <s4u_receiving_actor>`.
A big difference with twitter hashtags is that SimGrid does not
on the data you want to get from the mailbox. To model such settings
in SimGrid, you'd have one mailbox per potential topic, and subscribe
to each topic individually with a
-:cpp:func:`get_async() <simgrid::s4u::Mailbox::get_async()>` on each mailbox.
-Then, use :cpp:func:`Comm::wait_any() <simgrid::s4u::Comm::wait_any()>`
+:cpp:func:`get_async() <simgrid::s4u::Mailbox::get_async>` on each mailbox.
+Then, use :cpp:func:`Comm::wait_any() <simgrid::s4u::Comm::wait_any>`
to get the first message on any of the mailbox you are subscribed onto.
The mailboxes are not located on the network, and you can access
that marked as permanent receiver, you should call
``mailbox->set_receiver(nullptr)`` by the end of the actors so that their
memory gets properly reclaimed. This call should be at the end of the
-actor's function, not in a on_exit callback.

Note that Mailboxes, Hosts and Links are not handled thought smart
pointers (yet?). This means that it is currently impossible to destroy a
