I'm new to ask so when someone asks a question and answer space is blank does that mean anyone can answer or just an expert?
Anyone can answer. After you read a few you will find there are very few experts here.
The "answer this" space is for you to type your advice or answer.
You may answer any question. I usually answer unanswered questions by choice.
Anyone can answer and some are wrong so choose your answers carefully....
Usually in my questions I specify what kind of answers I'm looking for to help filter out some of the "others".
It means you can answer it. Answering questions will build your followers and sometimes it just feels good to help people
Any random person can answer it. There are a few of us on here that are regular answer-ers though.
Only an expert can answer it. Hence my presence here.
