I realise it's a deficiency in the SE system, but a new user (from memory) can't post comments to questions or answers, unless it's their own.
A lot of users throughout SE as a whole do this, post an answer that really should be a comment on a question or the answer in question because they can't offer said comment because their rep os too low.
How should this be handled?
For example, in this question:
There is a down-voted answer which someone else has come out in support of (rightly or wrongly) but can't add a comment because their rep is 1. But in the scheme of things, if this is in fact valid, then it could serve as a valuable comment and aid to future searchers.
For the interim I am going to manually create the comment for him and recommend his answer for deletion, but I'm open to suggestion on what the "norm" is
