By far the hardest thing we're working on right now is the ability for users to link their various accounts from all the Whiskey Media sites into one account. It's rough because we're trying to keep everyones unique usernames and profiles intact in a way that causes the least amount of confusion. I'll likely make a video on the whole merger process but for the meantime gander at this here screenshot and feel free to ask questions.  
 
Here's the main bullet points: 

1. Single sign on is free, you don't need to pay for it.
2. You don't need to do it (at least initially, we'll likely ask old users to make the switch within 3-6 months).
3. You'll be able to retain your different usernames for each site, though all new sites we end up building you'll have to use your main name.
4. People can't pick a main whiskey name that is already claimed on one of our sites already (no worry about land grabbing). This means that if your posting here with name "X", you don't have to worry about stealing your name, you already have it.
5. If you decide to get a paid account you will also need to sign up for a whiskey account.
6. All brand new accounts made after september 9th will work across every site, only you old folks need to have the hassle of merging accounts.
7. We aggregate your wiki points score across all sites and will use that score as the main barrier for wiki privileges.
8. Mods will remain unique to the site. So being a mod on one site won't make you one on the other.
