My template is not yet finished, but of course you will then be able to use it and I can help you with setting it up. Tomorrow I will be sending first version to some of "my beta testers"and hopefully not many bugs will appear so I will be able to release some version 1.0 soon.
If you just want to send data to WU you dont even need a website, many softwares allow you to do this directly, for example Cumulus, Weather Display, Meteobridge etc. Which software do you currently use/plan on using for your weather station?
