If I might make an odd suggestion. In the online gaming world, gamers (yes, I am one thats how I know this) tend to use VOIP for communicating while playing online. I do not know how you are hosting the site here, or if it's feasible, but if you were to have a TeamSpeak (https://www.teamspeak.com/downloads) server set up (it's free for non commercial purposes) it would give a whole new dimension to "chatting about Opels" and or helping each other out, because you know it's way easier to explain something with ones vocal cords then it is to do so with ones fingers. Just a thought.
