Hi Hive account@chrisaiki
Thanks for the idea and it definitely looks interesting. To join the Use-a-Thon as contestant, please see the instructions on how to join. Particularly this section:

How to particpate

To join the contest, participants pay an entry fee of 25 MB. The entry fee must be paid from a publicly attested Steem user’s Byteball wallet. This allows us to keep track of participants and to follow your progress on your blogs. All entry fees are added to the prize pool and distributed on a 10:5:2 ratio between the prizes.
Send your 25 MB entry fee to this address

That allows the Use-a-Thon jury to identify you and add you to the list of contestants also allowing everyone else to follow the progress of your project here
