-####How can I change my status
-You can set an account offline by long pressing on it and select temporarily
-disable account from the context menu. Other statuses like away, DND and N/A are
-not supported for simplicity reasons. Users tend to forget their status, other
-users ignore them and setting the status automatically would mean too much of an

+####Where can I see the status of my contacts? How can I set a status or priority
+Status are a horrible metric. Setting them manually to a proper value rarly
+works because users are either lazy or just forget about them. Setting them
+automatically does not provide quality results either. Keyboard or mouse
+activity as indicator for example fails when the users is just looking at
+something (reading an article, watching a movie). Furthermore automatic setting
+of status always implies an impact on your privacy. (Are you sure you want
+everybody in your contact list to know that you have been using your computer at
+4am?!)
+In the past status has been used to judge the likelihood of whether or not your
+messages are being read. This is no longer necessary. With Chat Markers
+(XEP-0333, supported by Conversations since 0.4) we have the ability to **know**
+whether or not your messages are being read.
+Similar things can be said for priorites. In the past priorties have been used
+(By servers, not by clients!) to route your messages to one specific client.
+With carbon messages (XEP-0280, supported by Conversations since 0.1) this is no
+longer necessary. Using priorities to route OTR messages isn't pratical either
+because they are not changeable on the fly. Metrics like last active client
+(the client which sent the last message) are much better.
+Unfortunatly these modern replacement for lagecay XMPP featurs are not widely
+adopted. However Conversations should be an instant messanger for the future and
+instead of making Conversations compatible with the past we should work on
+implementing new, improved technologies into other XMPP clients as well.
 ###Security
 ####Why are there two end-to-end encryption methods and which one should I choose?
 In most cases OTR should be the encryption method of choice. It works out of the box with most contacts as long as they are online.
