Few days back we described about Multiple Inboxes, which is on field as experimental feature.
If you forward all your work or school email to Gmail, you can use Multiple Inboxes to see your two accounts separately within the same browser window. Just listen to the following instructions.

Want to know about Multiple Inboxes feature from Gmail ?

•Just turn on Multiple Inboxes from the Labs Tab Under Settings.
•Then you have to setup a filter to auto archive all mail sent to your work or school address. To do this, rush to the Multiple Inboxes tab under settings and set up one of the panes to search for mail sent to your other address.
•(Optional) Use a “custom from” address so that replies will be sent from Gmail but as if they are from your other account. This way, your coworkers or classmates won’t know the difference.
Here you can use multiple inboxes to track of email sent to my college alumni address which you forward to Gmail. [ Thank You ]
