## Reconnecting to places
To permanently leave a place, see GNUNET_SOCIAL_host_leave() and GNUNET_SOCIAL_guest_leave().
When leaving a place its network connections are closed and all applications are unsubscribed from the place.
-# Methods
+# Message methods
-## _message
+## _converse
-A message sent to the place.
+Human conversation in a private or public place.
### Environment
-#### _id_reply_to
+#### _id_reply
Message ID this message is in reply to.
#### _id_thread
Thread ID, the first message ID in the thread.
-#### _nym_author__
+#### _nym_author
Nym of the author.
+FIXME: Are nyms a different data type from egos and person entities?
+Do they have a different format than any other entity address?
+Questions and thoughts on how to fix this in "questions.org"
+
#### _sig_author
Signature of the message body and its variables by the author.
-## Data
+### Data
Message body.
##### _gns_place
GNS name of the place in a globally unique .zkey zone
+FIXME: A custom _gns PSYC data type should be avoidable by parsing
+and interpreting PSYC uniforms appropriately.
+Thoughts on this in "questions.org"

#### Without GNS
##### _key_pub_place
Public key of place
+FIXME: _key_pub can't be the data type for GNUnet-specific cryptographic
+addressing. Questions and thoughts on how to fix this in "questions.org"
