Do you comment on other people's posts? That will help you get more exposure around the community and give you more opportunity for upvotes.

I have noticed that, being the middle of the summer, fewer people are online and voting for others. Remember, this is a community that thrives on everyone interacting with each other. The more you put into the community, the more you will have the opportunity to get out of it!

Good luck, and keep your head up! :)
