Good initiative from you. I suggest that as soon as faucet owners start joining your platform, add some convenient features for users:
-Chat box
-Internal exchange
-Some sort of missions with rewards
-List of faucets using MicroWallet
-More coins
-etc..
I also hope you implement good faucet protections as you know faucet abuse is pretty common and people must have high standards/Expectations because of how good Faucethub was doing.
Edit:
If you are someone who provides micro-wallet services, please advertise your site here.
Write a short description about yourself, your team, if any, your plans and anything that will help you gain trust from the users.
May the best ones make it.
