My School is in the process of selecting a CMS have narrowed it down to 4 separate ECMS. We have chosen Omni Update, Cascade Server, Plone and dotCMS. I have read all of the features and seen the doteduguru site's reviews but I would like opinions from people who use them and more importantly issues they have had with them. I know all of the positives of these CMS's but I would like to know the negatives, or things you expected but did not receive. Every CMS must have a fault in it somewhere. Some of these feature's lists are to similar...which is why I'm asking for negative "features". Any help would be greatly appreciated, anything from implementation from the system setup to the average user issues.
