New member here! Just figured I'd post an "I'm here" thread.
I'm also guessing that there's a spam prevention feature where you need to have a certain amount of posts before posting in certain areas, which would be why I can't reply to a topic in, say, the Virus and Malware forums yet.
I think that forum is really heavily moderated because it's a service that's run by experts. You can probably post a new thread asking for help, but I don't expect folks like you and me can reply to stuff that could potentially damage someone's system.
The rest of the boards seem pretty lax though.
