+Password reset

+If a user has registered an email address to their account using an identity

+Halp!! Synapse eats all my RAM!
+===============================
+
+Synapse's architecture is quite RAM hungry currently - we deliberately
+cache a lot of recent room data and metadata in RAM in order to speed up
+common requests.  We'll improve this in future, but for now the easiest
+way to either reduce the RAM usage (at the risk of slowing things down)
+is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
+variable.  Roughly speaking, a SYNAPSE_CACHE_FACTOR of 1.0 will max out
+at around 3-4GB of resident memory - this is what we currently run the
+matrix.org on.  The default setting is currently 0.1, which is probably
+around a ~700MB footprint.  You can dial it down further to 0.02 if
+desired, which targets roughly ~512MB.  Conversely you can dial it up if
+you need performance for lots of users and have a box with a lot of RAM.

+    HTTP endpoint for extracting data from synapse.
+
+    The streams of data returned by the endpoint are controlled by the
+    parameters given to the API. To return a given stream pass a query
+    parameter with a position in the stream to return data from or the
+    special value "-1" to return data from the start of the stream.
+
+    If there is no data for any of the supplied streams after the given
+    position then the request will block until there is data for one
+    of the streams. This allows clients to long-poll this API.
+
+    The possible streams are:
+
+    * "streams": A special stream returing the positions of other streams.
+    * "events": The new events seen on the server.
+    * "presence": Presence updates.
+    * "typing": Typing updates.
+    * "receipts": Receipt updates.
+    * "user_account_data": Top-level per user account data.
+    * "room_account_data: Per room per user account data.
+    * "tag_account_data": Per room per user tags.
+    * "backfill": Old events that have been backfilled from other servers.
+    * "push_rules": Per user changes to push rules.
+    * "pushers": Per user changes to their pushers.
+
+    The API takes two additional query parameters:
+
+    * "timeout": How long to wait before returning an empty response.
+    * "limit": The maximum number of rows to return for the selected streams.
+
+    The response is a JSON object with keys for each stream with updates. Under
+    each key is a JSON object with:
+
+    * "postion": The current position of the stream.
+    * "field_names": The names of the fields in each row.
+    * "rows": The updates as an array of arrays.
+
+    There are a number of ways this API could be used:
+
+    1) To replicate the contents of the backing database to another database.
+    2) To be notified when the contents of a shared backing database changes.
+    3) To "tail" the activity happening on a server for debugging.
+
+    In the first case the client would track all of the streams and store it's
+    own copy of the data.
+
+    In the second case the client might theoretically just be able to follow
+    the "streams" stream to track where the other streams are. However in
+    practise it will probably need to get the contents of the streams in
+    order to expire the any in-memory caches. Whether it gets the contents
+    of the streams from this replication API or directly from the backing
+    store is a matter of taste.
+
+    In the third case the client would use the "streams" stream to find what
+    streams are available and their current positions. Then it can start
+    long-polling this replication API for new data on those streams.
