Here are Gmail tips or tricks that you may want to know about
Use address aliases
Gmail doesn’t offer traditional e-mail aliases, but you can add a “+” to the end of your username to create one. For example, messages sent to username+alias@gmail.com is sent to username@gmail.com. This can be useful for setting up filters or figuring out who’s selling your e-mail address to spammers.
Dots or no dots, it’s your username
Did you know that Gmail doesn’t recognize dots as characters within a username? That means that if your e-mail address is username@gmail.com, then user.name@gmail.com and u.s.e.r.n.a.m.e@gmail.com are also yours.
oh! and do have fun.
