rlemon asked: you have encountered a low-quality issue where is it difficult to determine what the problem is; if a problem exists. Downvote, Edit, Flag.... which do you do first? and what associating comments would you provide the OP (if any)?
jrg asked for clarification: So we have a badly written question, correct? If so, my answer is edit, edit edit edit edit did I mention that I can edit the question?
rlemon clarified: Low-quality meaning poorly written, no information, bad english/grammar, bad formatting, ect..
Amith KK answered: I would leave a comment stating telling its of low quality, Edit it if I can and If the user doesn't respond In 2 days, I'd close as Low Quality
William answered: Edit! I believe that by editing instead of flagging you are setting the example to the community and the user on how to write better questions. I wouldn't leave a comment, because they might interpret it as me insulting them, and that is not the case. There are times when flags are entirely appropriate.
jrg answered: Using our wonderful selection of pro-forma comments, ask for more information if required (logs, what hardware they have etc), if its just bad formatting, English/grammar etc, just edit it and leave a comment saying that I edited it to try and help them get an answer. :)
Octavian Damiean answered: If it is problematic to determine the problem I would leave a comment to the user asking him to try to be more clear. I would definitely never down-vote a question just because I don't understand it. If I understand the problem but the question can be improved to be easier to understand then I would of course edit it.
Roland Taylor answered: Normally in such cases, I refrain from voting or closing until I have been able to gather some information regarding the question from the user, unless of course they seem to be just wasting time. In either case, I would ask the user in a comment what they were trying to ask, and if needed, provide assistance by editing or having a chat with them.
fossfreedom answered: I very rarely downvote - 5 in my whole history! I prefer to edit and improve. I do flag. I dont see a reason as mod to enforce "superpower" rights. Work with others. Give a question the 5 chances that it has at the moment. It really has to be a rarity to force me to use "superpower". After all, this is a community and we need to work through whatever issue is bugging us.
Bruno Pereira answered: Edit. Edit, edit, edit. If in doubt edit even further. Make things as good as they can be and within AskUbuntu's topics. If that is not possible take action based on what you have in your hands and flag, link in chat, ask other ppl's opinion on the matter or just ask for support to close the issue.
jokerdino answered: If I can understand the core meaning of the low quality content, I would try to edit it to make it more useful and meaningful. If that is not possible, then I would post it in the chat room hoping that someone else will finish off the task that I intended to start. I try not to downvote or flag when the problem is fixable. Regarding comments, I would ask the OP to be more specific and relevant and request to stick to the problem in hand.
