Reduce karma required for commenting
Apparently there is the issue, that new users with only few karma can't post comments (on other people's answers)(example). As a result some post comments as answers, since there is no other way.
If this is true, could we lower the amount of karma required for commenting?
Seems like a good idea to me, as long as we can avoid spam comments, which are mostly karma 1.
Related to this, low karma user not being able to paste URL is becoming troublesome...often it makes difficult to track which tutorial page the questioner is talking about.
I'd like to allow any links to ros.org even with 0 karma, if that is somehow possible to do.
