Curious onlooker

I stumbled upon this group while attempting to research the topic of making an unlimited number of cellular devices play an identical ringtone simultaneously. I have an IT-savvy business partner who could hand-hold me thru the growing pains of learning enough to at least sit quietly through a conversation and glean something from it, but I’m a bit of a self-starter in that regard, and have elected to become ‘baseline-conversational’ on the subject.

So, If there are any resources, schematics, picture-books, or other cool resources any of you might be able to offer, please fire awy!

Happy Holidays to you all
