How to Register as an Alt

[Ankamius]

I'm not sure what you mean by number 1.

It may not necessarily need it technically for a hydra. If someone registered it as their alt, that'll automatically let it activate. It's good practice to have the hydra registered anyway (if it's a secret hydra, a listmod should be able to help. if it's not, the thread is the better place).

There's a 15 character requirement for listing the mains of an alt. At least there was one.

That was the reason I had any troubles last time I made another account.
