I have been a Gmail user since it came out. Today I decided that I needed to rethink my "Labels" structure. Since there are not "sub-labels", I have started grouping together everything instead of splitting it all out in its own label.

Ex: instead of a label for each airline account, I have one called "Air Travel", and it holds everything, my check-in stuff, my reservations, my receipts, etc.

So, how do you organize your Gmail?

I guess this can be applied to other e-mail as well. Maybe I should try it in my Outlook as well. Instead of having a breakdown of clients and their projects, maybe I should just have a folder for each client or maybe just a "Clients" folder...
