I have a Twitter account for myself, associated with my primary, personal website. However, I run a few other sites as well, not really related to my own, and wonder about having Twitter accounts to correspond to those sites.
Does each Twitter account have to be registered with a separate email address, or can the same email address be used to register multiple Twitter accounts?
I'm not doing this for spamming or anything like, but simply to add a communication channel for these other sites. In the end, I'm the one that will be using these accounts.
