I would like to answer questions that sometimes I see here in Q&A, but I dont know if just memorable members can do it; I have none reps so maybe thats the reason, idk, :v
Anyone can ask a question and likewise anyone can answer questions. Memorable members typically do it because they have spare time to answer them, you're free to join if you have an answer to somoene's question.
Right now you're ASKING a question.
