I'm putting the final touches on a server-side alerting system for *A award searches. I've mostly got the code functional and the finished product should be along reasonably soon. Part of that process involves setting up the polling system. How often is too often? Keeping in mind that it will send you an email that the seats are available when that happens. Also, would it be of value to be able to register a mobile phone number to receive the alerts via SMS rather than via email? If the SMS thing happens it would likely only be for First Class members.
