I am sure you all have covered this topic a few time. So bear with me :)

I love peppers and am getting tired of spending a large amount of money on the seeds to plant each year. I mainly grow only heirloom plants and would love to save the seeds from my peppers too. I bag my tomato seeds so I don't have to buy them and so I can trade them aswell. Do I have to bag the peppers too. I want to get true viable seeds. Is there a distence between plants so i dont have to bag? Any info would be fabulous on this mater. Also I only grow sweet to mild peppers if that matters.
