I'm using webmin on my internal lan server now. Was using it on my hone server quite successfullly. Coop was going to install web-cp for me on my internal lan (I had given him access to it) but apparently it has too many issues so we went back to webmin which I am familiar with.
When I had my home network up, I had as many as three forums, and seven static html sites on there. That was the highest point. Granted none of the forums were large but I did okay. Liz
