The best feature is that it has all three in one place, so there's no need to keep track of 3 different systems if you are looking for an answer or want help solving some problem related with your business/productivity system etc.. It can't handle images very well but otherwise works fine! Also the support team from AIMSolutions was really good as they helped me out during my testing phase even though I had problems understanding how it worked sometimes because this product seems quite complicated at first glance (but once used its pretty easy). They do not have any other features apart form wikis which makes them seem like their only focus liekly beinqg just another wiki software provider who does nothing else than offering us products sucha nd services relatingt owikis without adding value themselves. Maybe make tutorials available via video tutorial.
