My vote is for Star
Long before I even joined the forums, I could see that she was very active. Skimming through the threads, updates, and the latest fun house jokes, I could see she was at the forefront of the threads. Helping community members with their signatures, anime recommendations, and even personal issues.
She is a very sociable member, and fun to chat with in the shoutbox. In fact without her, the shoutbox would be less bubbly with the lack of ( ^_^ ) emotes. She says hello to everyone, and even spends her 24+ hours of sleeplessness just to talk with other members.
The Miner of the Month is someone who contributes a positive impact on the Total Miner community. A member who sets a standard for others in the community as a positive role model, not just for the months leading up to their award.
I believe she embodies this aspect with flying colors. My vote is for Star.
