How many levels of escalation are there on fixya

Escalate is a process on FixYa that ensures each and every question you ask receives the attention it deserves.
When you ask a question on FixYa it initially goes to our Level 1 Experts. If these experts do not have an answer they can immediately escalate it to our Level 2 Experts, who have more experience solving problems on FixYa and are more likely to have your solution. This same process occurs when Level 2 Experts escalate a question to Level 3.
Questions can also be escalated by time-- if your question has not received an answer three hours after being posted it will automatically be escalated to Level 2; no answer after 12 hours of being posted will automatically escalate your question to Level 3.
