To ask a question to someone, simply click on "Ask a question" in the Questions tab or use the little pencil icon on the top right if you don't send it.
Once you have clicked on it, you will then be able to compose the question you want and then select who should receive it. You can choose between one person only or a multiple number of people. The system can also recommend who might be the best persons to answer that specific question in your contacts or with other users on Instantgo.
As soon as you send your question, the users you have selected will receive a notification and will see your question in their pending question tab. If you select users in your contact list who is not yet a registered user on Instantgo, they will receive your question by SMS with a link to answer them within the app.
