I sure can but not a lot yet, I've bought IdeaMason and I really like it, it is however a complex beast and I havent worked it all out, It has options to do just about anything I might want to do in the way of idea sorting tagging and so on, but I don't see it as a replacement for those tools like endnote certainly as it stores data in a proprietary format that requires Ideamason to be on the computer you are using. (endnote may use its own format to, i don't know, but it seems to be a common application around universities and the like). So far I've only used it on one essay but like Douglas Adams, I seem to like the sound that deadlines make as they whoosh past, so i went back to just finishing it off in word, only a day late

) After the exams are over I'm going to have another go at it without the pressure of actually trying to meet a deadline and will be able to dig through its options, but my initial impression as an undergraduate student it will, i think, meet all my needs for sorting tagging categorizing references and so on that i need and of course it can be used as a journal keeper to do list, all of those sort of things, though you wouldn't buy it to do those functions alone, once i've moved on from studying (if i do, might retire as a student yet lol)
