I asked this question in another thread, but I managed to create some confusion, so I'm asking again.

When you are gathering the information and analysis that you need to write copy, how do you store that information? Things like lists of benefits, features, testimonials, product details, headline ideas, client/customer results and all the info generated by the questionnaires and interviews that you do?

Is there a software product that can help with this? Do you have it all on post-its and bits of paper on a cork-board? Do you put it all into Microsoft Word or Excel?

Is this type of thing a trade secret and that's why no one has answered my original question?

Someone please H-E-L-P-!
