About Linux and MacOS:
Regularly I get questions about the availability of ZW-Scoring for Web, Linux or MacOS.
Leo Eggink has built ZW with Visual Basic 6 specifically for the Windows platform. Right now I am converting it to VB.Net, still on the Windows platform, which is quite a task in itself due to the many differences between VB6 and VB.net. The latter is more or less Object Oriented, which I try to use as much as I can. I hope this will make a future move to rebuilding ZW in the Java language more easy. This is needed before thinking about releasing versions for Linux and MacOS.
ZW on the Web is also something I am thinking about, but at the moment this has no priority.
