I would also appreciate an invite if someone can spare one.

From the CME site:

B1. What is a CME identifier?

CME identifiers are assigned in the format 'CME-N' where N is an integer between 1 and 999, for example, "CME-123". To accommodate space-deprived anti-virus products, CME identifiers can be abbreviated (e.g., M123 or M-123), but the official format (i.e., CME-123) should be used in places such as Web pages, alerts, encyclopedias, etc. Additional digits will be added when the remaining unused identifier space becomes too small. For the sake of successful text-based comparisons, leading zeros will always be omitted in an identifier, e.g., CME-00123 will always be written as CME-123.
