In order to do this properly we would need to use an "SMS Gateway" service, which would have additional costs. Basically we would need to charge the association $0.01 per outgoing text message. For most associations the number of text messages per year for just the game officials module would be in the 5,000-10,000 range, or $50-$100. That may not sound like much, but considering that's almost 10% of the cost of the entire site, it seems like that might be hard for some associations to justify. Perhaps we're wrong on that, and I'm sure not everyone feels the same way. For large associations with several hundred teams, we're talking potentially thousands of dollars.
The other issue is figuring out how / when to charge for the true texting service. It would almost have to be an annual fee based on estimated usage ahead of time rather than a fee assessed after-the-fact based on actual usage. That means we'd also have to estimate those costs based on a worst-case scenario and if actual usage is lower than expected then the cost per text is pretty high.
If an association is still good with all that, then we can probably move forward with offering it as an add-on option for the site. We've actually trialed this in the past so it's more-or-less already built but we could never make the numbers work to what we thought associations would consider fair.
I personally also feel that just because a teen thinks that they can get through life not checking email doesn't make it right. They should probably learn sooner rather than later that the 'real world' which they are about to enter will require them to have strong email skills. Timekeeping / refereeing is a job and it should be perfectly fine for the employer to set the rules rather than the employees. But that's just my personal opinion.
