1) We need devs to make a very secure, working wallet.

2) We need to identify the problems affecting Litecoin and how we can solve them with Litecoin Ultra (and how the devs will do this).

3) We need devs that will allow others/the community to mine this coin.

4) The main purpose of this coin (I assume) is to be a lighter and faster alternative to Litecoin, and if this is our purpose then the whitepaper must detail how and why this coin should be adopted, and why people should choose it over Litecoin etc.

5) We need knowledgeable devs who have the skill and know-how to make this coin faster, even if it involves running on a better blockchain/infrastructure etc. (Something like the tangle would be good).

6) Once our purpose is established and we have devs, then we can start the whitepaper with a clear purpose of what this coin is and why it should be used (we'll need to know this if we are going to convince people to mass-adopt it).

Does anybody else have any ideas?
