I've often encountered the following situation: Someone posts a question, but the question can not be answered because:
- Some important information is missing. In this case, it would be very helpful to let the questioner know that.
- The issue is caused by a bug but there is no workaround available. However it would still be very useful if someone told the questioner that and maybe posted a link to the corresponding bug report website.
In either of these cases you cannot do this by posting an answer, because it will be downvoted and deleted.
My question is: What can I do in such a case if I have less than 50 reputation? My motivation is to help other people, not to earn reputation (that's only secondary).
