Weird...no testimonials in your forum for the 1.0x version. I have one for you!
I run the 1.07 or what on my joomla 1.5 sites.
It feel like I just bought it, but in reality it has been working flawlessly on my 8 sites four months now. Really easy to install and use, and putting up a new site is almost too easy nowadays

At the time I'm struggling with installing the joomfish on a slave site, but that's the first problem I've had on 8 sites! Well, besides a couple small rights problems, because our server have separate www and ftp accounts, but I would blame the server rather than the component for that.

If you have a couple of Joomla sites this is a must have component in my opinion.
