I installed this to test if it was the thing I was looking for. It wasnt. Can't say so much about the functionality BUT...do NOT install it if you think youre going to uninstall it afterwards. I tried to uninstall the normal way - didnt work. Then I discovered my site was messed up. Nothing worked except for the frontpage! I had to delete all the dirs by hand, cleaned up my database by hand, then tried to uninstall it the normal way (now it worked) and my site do now work again after this. Until the developer fix this serious bug, think twice before try out this extension.
Very sorry you had difficulties. I have heard of rare situations where there have been install/uninstall difficulties but I do not know what is causing the problem. Many people use this extension without problems so I do not believe it is a general problem. You are always welcome to contact the developer for help.
