 24+            Unfortunately SHA-2 RSA keys are <strong>not</strong> currently supported.
 25+        </p>
 26+        <p>
 27+            Unfortunately, due to a shortcoming in Go’s x/crypto/ssh package, Soft Serve does
 28+            not currently support access via new SSH RSA keys: only the old SHA-1 ones will work.
 29+            Until we sort this out you’ll either need an SHA-1 RSA key or a key with another
 30+            algorithm, e.g. Ed25519. Not sure what type of keys you have? You can check with the
 31+            following:
 32+        </p>
 33+        <pre>$ find ~/.ssh/id_*.pub -exec ssh-keygen -l -f {} \;</pre>

 86+            How do I update a list?
 87+        </h2>
 88+        <p>
 89+            Updating a list requires that you update the source document and then run the <code>scp</code>
 90+            command again.  If the filename remains the same, then the list will be updated.

 97+            How do I delete a list?
 98+        </h2>
 99+        <p>
100+            Because <code>scp</code> does not natively support deleting files, I didn't want to bake
101+            that behavior into my ssh server.
102+        </p>
103+
104+        <p>
105+            However, if a user wants to delete a post they can delete the contents of the file and
106+            then upload it to our server.  If the file contains 0 bytes, we will remove the post.
107+            For example, if you want to delete <code>delete.txt</code> you could:
108+        </p>
109+
110+        <pre>
111+cp /dev/null delete.txt
112+scp ./delete.txt {{.Site.Domain}}:/</pre>
113+
114+        <p>
115+            Alternatively, you can go to <code>ssh {{.Site.Domain}}</code> and select "Manage posts."
116+            Then you can highlight the post you want to delete and then press "X."  It will ask for
117+            confirmation before actually removing the list.
118+        </p>

124+            Can I create multiple accounts?
125+        </h2>
126+        <p>
127+           Yes!  You can either a) create a new keypair and use that for authentication
128+           or b) use the same keypair and ssh into our CMS using our special username
129+           <code>ssh new@{{.Site.Domain}}</code>.
130+        </p>
131+        <p>
132+            Please note that if you use the same keypair for multiple accounts, you will need to
133+            always specify the user when logging into our CMS.

 39+            Content in {{.Site.Domain}} blogs is unfiltered and unmonitored. Users are free to publish any
 40+            combination of words and pixels except for: content of animosity or disparagement of an
 41+            individual or a group on account of a group characteristic such as race, color, national

 43+            immediately.
 44+        </p>
 45+        <p>
 46+            If one notices something along those lines in a blog please let us know at

 60+        <p>
 61+            We are committed to zero browser-based tracking or trying to identify visitors.  This
 62+            means we do not try to understand the user based on cookies or IP address.  We do not
 63+            store personally identifiable information.
 64+        </p>
 65+        <p>
 66+            However, in order to provide a better service, we do have some analytics on posts.
 67+            List of metrics we track for posts:
 68+        </p>
 69+        <ul>
 70+            <li>anonymous view counts</li>
 71+        </ul>
 72+        <p>
 73+            We might also inspect the headers of HTTP requests to determine some tertiary information
 74+            about the request.  For example we might inspect the <code>User-Agent</code> or
 75+            <code>Referer</code> to filter out requests from bots.

21+            In order to have a functional account at {{.Site.Domain}}, we need to store

23+        </p>
24+        <p>
25+            Because we use public-key cryptography, our security posture is a battle-tested
