What are all the ways of enhancing mylot earnings?

Yes you can also respond to blog posts (I believe) and you can respond to news articles to increase your earnings. To make more it really just takes dedication to the site, with long hours, etc. You can make more then the $10.00 monthly but it also depends on how much time you allot for mylot.

We earn for all our OWN activity so whatever you do will help your earnings increase. If you start a discussion you will earn only if it receives a response and then, after that, you will only earn if you go back and comment on the responses with an intresting quality post. In the FAQs we are told: 'Post quality content. For example, generate discussions that engage other users and provide insightful responses and comments to other users discussions to further the topic' http://www.mylot.com/o/faq/faq6.aspx#14 Commenting is what turns a simple question and answer into a discussion and here we earn for discussing. Hope this helps you and others too

You've pretty much listed what mylot is all about. There is also uploading pictures to discussions and topics but mostly what people do is posting discussions and responding to others. If this is not something you're interested in, there are a lot of other legit sites out there you can try. Good Luck.
