When cropping one image the face needs to be centered and proportional.
Example:

Step 1: (Main details)

1. Write part of the series title to get hints (for example write "eva" for Neon Genesis Evangelion), if you're adding several characters for one series you only need to do this once
2. Click the hint to add the complete series' title to the field, if the series does not exist you'll have to write the complete title manually
3. Write the Character name, you will get the percentage of similar matches if any.
4. Choose one image to crop (Local or Remote)
5. Add other aditional details if you wish (alt. character names, description)
6. Choose the cropping area (It's recommended Custom if the image isn't already cropped)
7. Click Insert/Suggest to go to step 2 (or to finalize if you didn't choose custom cropping)

Step 2: (Custom Cropping)

1. Click the dark preview area to call the crop selection to desired spot
2. Resize the selection until you're satisfied (You may preview the result below)
3. Click "Insert/Suggest" to finalize or Click "Insert/Suggest and crop this image again" to extract more characters from the same image

Step 3.1: (Only for Suggestions and Registered Users)

1. After you're done suggesting all characters, check your profile and click "Pending" separator for further editing/confirmation

Step 3.2: (Only if you started the series)

1. After you're done suggesting all characters for the series you started you may load the series page (check your profile contributions and click the series link) and add further details (Alternate titles and/or description) by clicking the edit icon. If you started the series through character suggestion you'll have to wait until at least one character is inserted before being able to edit the series' details.

Alternate forms are secondary forms where characters look different.
To add alternate forms load form manager through the link on character details.

Alternate form common to more than one character

If two or more characters have the same alternate form, you'll have to add the form for the first character and then make a link for each of the other character(s).
Note that the bookmarks of common forms will always use the first character as representative.

Choosing the Main Form

If a character has many forms the main form will follow the priority list below (choose the first that applies):

1. Human form
2. Most relevant
3. First to appear

bookmarks allow users to build a favourite list for their profiles.
To bookmark a character (or an alternate form) just click the at character page, when it becomes the character is bookmarked, to unbookmark just click again.
It's also possible to bookmark forms, to do it just go to the form manager by clicking the symbol at details.

The Rank system attributes each character a position according to the votes received. Only characters which received more than X votes are attributed a rank.

Each time a character or a series is modified a revision entry is generated. Revisions allow users to suggest additional details or improve the existing ones. If the user making the revision is not the original submiter the revision will be pending for approval.

Groups purpose is to organize characters that have something in common (part of a team, family...)
