On: I just lost my wallet on the way home from work

Gmail ignores periods in emails. It also ignores everything after the +.

So if your email is bob@gmail.com you can also use:

b.ob@gmail.com, b.o.b@gmail.com, bob+alice@gmail.com,

You can use the second one to do filtering. I.e. use a different +{filter} for bills, entertainment etc.

bob+bills@gmail.com for bills. bob+spam@gmail.com for sites you know will spam you etc.

then setup mail rules to filter based on the +

What if my email IS a.bob.mail@gmail.com, if someone registers abobmail@gmail.com are they getting my emails?

There's a slight chance the gmail developers would have thought of that scenario.

no, Gmail does check for that during registration. But you could use those two different email addresses to create two separate accounts somewhere else.

I knew about the + sign, but not about the period. Thanks for that - will come in handy!
