What should I do when, after posting an answer, I'm asked in a comment for further clarifications and/or a different solution (but still in-topic) and I don't know anything more?

Should I answer that I don't know or should I just leave it at that? The etiquette in this site is different from that which usually applies in forums...

  • Does the answer in question still, in your opinion, answer the question as originally posed?

  • @JosephWright: I posted it because I thought so, but actually I gave only a partial answer. This is the post I'm talking about. (Sorry, I made a mess with past comments, I didn't want to be a bother.)

  • Use comments to get the unknown further information. Comments are meant for further followup and clarification or even invite the User(If willing) to the Chatroom to avoid long comment history. Commented Jan 26, 2014 at 19:47
  • @texenthusiast: the problem is that I posted an answer, but I don't know how to answer the question asked in a comment of my answer.

    Option 1. Mention what's missing in your answer as note and improve later, It's no sin to say I don't know, I know this much, but I will improve(If you wish so). Option 2. If you don't feel good, delete the answer and Post an answer once you find it that matches OP requirements. Commented Jan 26, 2014 at 20:01

    In addition to @texenthusiast 's nice classification, the options are not equally weighted. Delete the answer only if you are really sure that it can't fly for anybody. Often I gather fragments from partial answers in a few questions for my final fix/solution. Besides, just say, I can't see right away how but I'll come back to this and please come back if you find a way :)
