I've been using AEC for almost a year now. I have to say when I first came across it...it was a gold mine! It has so many aspects that I love about it...too many to list. It's in fact so great and complex that it gets to be almost too complex for simple use...there are so many options and configurations that it can get confusing to use and set up what I would think should be simple features. You can tell right off the bat that this is a very well developed and thought out program. However, the one thing that does need work is the support...however it seems the owner is in the process of working on it. One big thing I do not like at all is that you must be a paid member to access the forums now. I have to be honest to say that when the forums were free...I wasn't impressed with them as I have with "other ones" one in particular open source component. I have to say I'm more than happy to help and add comments/posts to help others but not so much when I have to pay just to access them?!? I've donated back when this was a free component because I was impressed...however have much less interest in the idea I have to pay for forum information if I continue to use the software. I'd rather pay a flat fee rather then have to pay again and again over time...if in need of some help or an update.
