I constantly find that many deviants, new and otherwise, simply do not know how to suggest a Daily Deviation.

Just to make sure we are all on the same page here:
FAQ #61: What is a Daily Deviation?

Info to Know

The only rule applied to Daily Deviations is that a deviant may not receive more than one Daily Deviation within a period of three months.

All deviants, regardless of popularity, are eligible to receive Daily Deviations.
Popular deviants are still deviants and will not be disqualified on the mere charge of being popular from receiving a Daily Deviation.

Any deviation may possibly receive a Daily Deviation.
This is regardless of the amount of views or favorites it has garnered.

You are ALLOWED to suggest YOURSELF. Just don't abuse this.

Suggesting

The following are not rules on how to suggest Daily Deviations but rather guidelines that help staff capable to select Daily Deviations better and more quickly process suggestions.

To suggest a DD, send a note to the desired staff member.
Please, DO NOT suggest the same deviation(s) to multiple staff. Doing so can cause confusion and possibly your suggestion being ignored.

Those who can currently select and where they select from can be found in FAQ #18: Who selects Daily Deviations and how are they chosen?
It is preferred that the subject of the note is entered as: "DD Suggestion" or something close to that effect.

In the note a thumb to the deviation should be included.  This is not a link, it is a code.
The thumb code to any deviation can be found near the
bottom right corner of the Artist's Comments box.
A complete thumb code will look like:

:thumb1234567:

It helps to include the reason why you believe it deserves DD status but this is not needed.

Now you are read to send the note! BUT WAIT!!
Make sure that you are sending your note to the proper staff member. (Carefully recheck FAQ #18: Who selects Daily Deviations and how are they chosen?)

I sent my suggestion.. now what?

You don't have to do anything else!

ostit: The note may not be replied to or read for an extended amount of time. This is usually due to high amount of suggestions that some staff receive.

I HATE THIS DD!!!

Please keep in mind that a DD is in NO way an award but rather a FEATURE. A feature that is up for twenty four hours only.
