I sent today a text message to 15 people. Some of them replied to me (at least that's what they thought). But instead of just texting to me they texted to all 15 people. And since I did not know better I then also texted back to all 15 people although I wanted to text only to two of them in two individual messages. Is this normal that a text that I send to several recipients becomes some kind of group thread and when anybody replies it goes to all people of this group? Is it possible to prevent something like that from the very beginning - can I send a text message to several people without making a group thing out of it?
