Everything here is answered by one person, so there is no queue to work through — but where you ask decides how quickly it lands.
Support tickets
Support in the navigation opens a ticket. Pick the category that fits — including This Website for problems with linkrobins.com itself — and you get a thread you can follow, with every reply in one place. Tickets need an account, which is the same account your dashboard uses.
Before you have an account
The Contact link in the footer sends a message straight to me by email, with your address as the reply-to. Use it for anything you want to ask before we work together, including consulting.
Something that did not work
Say what happened and roughly when. For a monitor, give its name; for an extension, the forum it is installed on and what you expected it to do. That is usually enough to find it on my side without a second round.
Refunds
Ask on Support and explain what happened. A refund goes back through Stripe to the card that paid.
Tips
Uptime monitoring and the extensions are free. If they earn something from you, the Tips page takes any amount, and needs no account.
