I am quite new at all this so here goes - I currently have a single domain name and hosting (starter package) through TCH. Someone I know wants me to put together a page for a club of thiers and I wish to do this through TCH also. The original page I have with TCH uses little bandwidth and the page I will be making will use little bandwidth as well. Is there a way to combine the hosting for the two domain names or will I have to register the hosting separate? How would I do this? Thanks
