The helpdesk at helpdesk.nabzclan.vip is NabzClan's support desk. You open a ticket in one of seven sections, the staff read it, and the answer comes back on the ticket.
Use it when the matter is private or needs a decision from staff: a problem with your account, a scam report, a ban appeal, a copyright or privacy request, a site bug, or a partnership or press enquiry.
Do not use it for general sideloading questions. Those get faster answers, from staff and from other members, in the iOS Sideloading & Signing forum on https://nabzclan.vip. The Sideloading and signing help articles in this knowledge base cover the most common errors.
Staff accounts are labelled as staff, and who they are is listed at https://nabzclan.vip/threads/40/.
Which section fits your problem? See "Which ticket section should I pick?".
