Christian Chat is a moderated online Christian community allowing Christians around the world to fellowship with each other in real time chat via webcam, voice, and text, with the Christian Chat app. You can also start or participate in a Bible-based discussion here in the Christian Chat Forums, where members can also share with each other their own videos, pictures, or favorite Christian music.
If you are a Christian and need encouragement and fellowship, we're here for you! If you are not a Christian but interested in knowing more about Jesus our Lord, you're also welcome! Want to know what the Bible says, and how you can apply it to your life? Join us!
Far as being a mod, you have to prove yourself before they would even consider it. I don't know the details of what they expect, but i suppose a minimum time that you've been on the site, no serious reports against you, having an overall good reputation on the site and support from existing mods.
One catch though, if you ask to be a mod, you are automatically disqualified from becoming a mod.
Far as a support expert, first you're pretty new, so i don't think they'll want to have someone they don't know representing the site. They also wouldn't know that you have the ability. But really, that's why they have the User2User Forum, as GRA pointed out. People with any kind of tech questions from the site itself to PC problems can be posted there to be answered by anyone who has the skills to answer. So if you like to help with that stuff, just keep an eye out in that section.
