Louise has already posted about In Veglia.
Have navigated around and found some great sites. Really good for learning Italian (that is to say not say easy to read if you don't speak Italian, great if you want to start learning - heck why not)
Main link here at Gionata seems from what I can tell to be an Italian LGBT Christian site with an incredible amount of content already - as well as links to In Veglia.
It's a great site and I hope to pop in and out as my Italian (...) improves.
