Please make it clearer that help desk is not a bridge autoresponder

Hi!

The current “Bridge Relay Help” screen puts a terrible load on the support as it is. There is currently no layering and it confuses users.

We see many messages with a body of “get bridges” sent to the help desk instead of BridgeDB.

Would it be possible to better frame the three options? An idea could be:

If you are unable to connect to the Tor network, […] Here are three way you can learn
bridge addresses:

1. Through the web
------------------

Use a web browser to visit […]

2. Through the email autoresponder
----------------------------------

Send a mail to bridges@bridges.torproject.org […]

3. Through the help desk
------------------------

Politely ask bridges by mailing help@rt.torproject.org. Please be nice, this will
take human efforts here.

Or something like that…
