I made a Reddit account but I cant post anywhere because it says I need to have 200-300 karma and be active. The only way to get karma is by other people upvoting your posts so I fail to understand how I will ever be able to gather the karma if I cant post anywhere.
I have been victim of that problem as well. You are just going to have to be patient and post a few things, comment here and there it does not take that long to build up enough karma.
