Hi Hooi Peng,
Atlassian Support is actually located at this website : support.atlassian.com.
As for your question, I don't think the group jira-superuser is a default group in JIRA. It should only be jira-user, jira-developer and jira-administrator. Please check if this group was created by some of the admins.
where you got this group: jira-superuser from. it is not a default group i guess.
afaik default groups are jira-users, jira-developers & jira-administrators
there is a documentation availabe about how to set up jira-system-administrators and configure global permission to access trimmed admin operations
