The most simple version is 0.5b. The most recent versions are a little more complex.
If you downloaded the version 0.8b and show some warnings in the module. Please download again the component and the module, because the first upload has an important bug on both extensions.
The version 0.9b only works in Joomla! 2.5.
And the bad news is that there are some bugs.
So my opinion: if this works for you the way it is, that's terrific. If not, look for something else.
It does exactly what is says.
I would rate this 4 stars becouse i hardly need a category feature in this extensions to be perfect, but once it does what it says it deservs the 5 stars.
Hermes, please make a new release with a categorization feature for the births/events then your extension will have a jump in light years.
I didn't know about the JoomFish extension, but I read about that, and may be in a future release this component will have support for it.
