You can email us a new mnemonic device, with an explanation, at info@mnemonic-device.com. We'd really appreciate it if you search the site first to check whether your mnemonic device happens to already be on there.
Got a suggestion for a change? You can email us that too - just include the link to the mnemonic device it's about.
We'll check the inbox periodically.
Thank you!
