I joined yesterday. I spent a few hours browsing to get the feel of things, then added an answer with some code, for which I got some reputation points.
Today, I asked for clarification on another question, which I now realise I'm not supposed to do. And yet, I can see hundreds of examples where folk ask for clarifications on bad questions.
I now find that I am in a position to answer at least two more questions, but the system tells me: "Sorry, we are no longer accepting answers from this account."
If I look at my details, I can see no rejected answers, or in fact, anything negative.
Could someone who knows enlighted a frustrated newcomer? (To Stack Overflow, that is.)
