I'm going to give you some advice. Although I have never made a podcast I do know what makes a bad one. I have listened to more than my fair share of awful tech podcasts.
If you pick some random "teens" from a forum who claim to know their stuff and then just talk to each other with a microphone you are going to end up with something rubbish. You need to do a lot of planning before each episode and make sure that everyone involved does some research and knows what they are going to say. There is nothing worse than people who just babble on about something they know nothiing about for half an hour. Also, have you decided what exactly you are going to cover. You can't just talk about "tech", are you going to cover the news or are you going to do things like "howtos" or both?
Anyway, my point is, you need to put some time into planning.
