In forum.

If you use standard style sheet, then Administrators are red, Moderators - blue, Checked green and this is set by the following lines:

/* User Group Marks */
a.groupModer:link,a.groupModer:visited,a.groupModer:hover {color:blue;}
a.groupAdmin:link,a.groupAdmin:visited,a.groupAdmin:hover {color:red;}
a.groupVerify:link,a.groupVerify:visited,a.groupVerify:hover {color:green;}
/* ---------------- */

Users group is not indicated here and its color is assigned by the first lines of the style sheet, i.e. this is the color of common links. If you want to use your own color for Users, then add a line for groupUser.

/* User Group Marks */
a.groupModer:link,a.groupModer:visited,a.groupModer:hover {color:blue;}
a.groupAdmin:link,a.groupAdmin:visited,a.groupAdmin:hover {color:red;}
a.groupUser:link,a.groupUser:visited,a.groupUser:hover {color:#A8C9E2;}
a.groupVerify:link,a.groupVerify:visited,a.groupVerify:hover {color:green;}
/* ---------------- */

Each new group has the designation groupOther(1-10), as you may add 10 groups. Group number in this case means addition order.

/* User Group Marks */
a.groupModer:link,a.groupModer:visited,a.groupMo der:hover {color:blue;}
a.groupAdmin:link,a.groupAdmin:visited,a.groupA dmin:hover {color:red;}
a.groupVerify:link,a.groupVerify:visited,a.groupVerify:hover {color:green;}
a.groupOther1:link,a.groupOther1:visited,a.groupOther1:hover {color:Yellow;}
a.groupOther2:link,a.groupOther2:visited,a.groupOther2:hover {color:DarkCyan;}
and so on.
/* ---------------- */

A color may be assigned both by an English name and RGB hex code.

Other designations of users.

On forum main page:

1. Greetings to our new member - class="lastUserLink" (if it is not assigned, then has the color of a common link)
2. Happy Birthday! - class="userBirthdayLink" (similarly)
3. Forum moderator - class="forumModer" (similarly)
4. Thread author - class="lastPostUserLink" (similarly)

The same classes of p. 3 & 4 are inside forum, on page of sections and forums.

On page with messages:

1. Forum moderator – the same class="forumModer"
2. User’s nickname - class="postUser"
3. Group name - class="postUserGroup" - Attention! It’s not a link, but a plain text and the class applies to both words – e.g., group: Moderators

On site.

On site group names are also determined by the classes groupModer, groupAdmin, groupUser etc.

When changing group color, check whether the page template has the address of the file where you make changes.

The following line must be in the template:
