Its a huge whiteboard and really I don't have many projects at all. I mostly do offline marketing and I have just started to go into IM for myself.
Most of my offline clients are just a few keywords, organic Seo and ppc management.
Did that for a few years, then decided to switch to Keepass.info for the login information, and also keep details in Evernote and use a tag to group all the sites together under one view when I want to check on them.
