One of the nice features of gmail is you can have n number of accounts tied to your normal email - with emails coming to you and being addressed properly. This trick is used by folk in the software testing and QA business. I used it to test my filters and visibility in the community apps I am building. The trick is to add a +x to your account - when previewing, or making fake accounts.
Saves you typing in the email every time if you switch between ‘normal’ email accounts. M
