Hetty I sent him to your Forum.
He is a link to some pretty amazing information on cactus and other succulents.
I created a Locked Sticky Thread in the Sempervivum Forum for reference sites. I added his site to the list, then tree mailed him with the link to the Reference Thread. Then I deleted the new thread he had created. I explained to him that by placing it there it would be easy to find when people were looking for reference information.
The thread "Sempervivum Reference Sites" in
Sempervivum forum
He could be a very helpful person to your forum, he is from Italy and succulents are very big there.
