-But it isn't as clear cut when dealing with status.net, identi.ca and other network providers. You are encouraged to be **very** cautious when other network members are in a group because it's entirely possible for your private messages to end up in a public newsfeed. If you look at the Contact Edit page for any person, we will tell you whether or not they are members of an insecure network where you should exercise caution.

+Once you have created a post, you can not change the permissions assigned. Within seconds it has been delivered to lots of people - and perhaps everybody it was addressed to. If you mistakenly created a message and wish you could take it back, the best you can do is to delete it. We will send out a delete notification to everybody who received the message - and this should wipe out the message with the same speed it was initially propagated. In most cases it will be completely wiped from the Internet - in under a minute. Again, this applies to Friendica networks. Once a message spreads to other networks, it may not be removed quickly and in some cases it may not be removed at all.
+
+In case you haven't yet figured this out, we are encouraging you to encourage your friends to use Friendica - because all these privacy features work much better within a privacy-aware network. Many of the other social networks Friendica can connect to have no privacy controls.

+Profiles, Photos, and Privacy
+=============================
+
+The decentralised nature of Friendica (many websites exchanging information rather than one website which controls everything) has some implications with privacy as it relates to people on other sites. There are things you should be aware of, so you can decide best how to interact privately.
+
+**Photos**
+
+Sharing photos privately is a problem. We can only share them __privately__ with Friendica members. In order to share with other people, we need to prove who they are. We can prove the identity of Friendica members, as we have a mechanism to do so. Your friends on other networks will be blocked from viewing these private photos because we cannot prove that they should be allowed to see them.
+
+Our developers are working on solutions to allow access to your friends - no matter what network they are on. However we take privacy seriously and don't behave like some networks that __pretend__ your photos are private, but make them available to others without proof of identity.
