I can't find this anywhere else, and have posted it before at the end of an obscure post, so I thought it may be better to share the tip in a thread of its own. Signing up for mutiple accounts on something like Twitter is a pain in terms of needing a unique email for every account. A simple way to do this is using a single gmail account and aliases. (in the example below I can't use email address format as I'm a n00b, so after username don't forget to add the rest of the address) 1. setup your gmail account e.g. username 2. Use this to sign up for your first account in, say, Twitter 3. The next Twitter account you sign up for you use the alias email - username+1 Any mail for username+1 will go to the original username mailbox 4. Repeat using username+2 etc. etc. etc. It's a great way to sign up for many accounts and administer them all under one roof. Of course for Twitter accounts you'll also need to use proxies to avoid phone verification, but thats another matter.
