I need to get more information from a user on Ask LibO, so that I am able to answer their question. However, I am unable to comment on questions due to not having enough karma. How can I go about doing this?
@crazyskeggy – I’ve added 10 “karma points” to your “reputation” (via moderation) for adding comments to answers and questions. 
Update: Required karma points for adding a comment is now: 1 karma point.

Only problem: Many posts don’t have enough info, so I can’t answer them without asking for more info, via comments which I wasn’t allowed to use. Do you see the loophole for us newbies?
@crazyskeggy - addtitional to the karma points manj_k gave you, you also can write an answer to ask your questions.
