I'm building out 6 sites for one of my clients. One of the sites supports their corporate brand and the other 5 each support a line of products. I need to set up an email list for each of these sites (one list for each product line plus a corporate news list - 6 lists in total). But, I need to let users subscribe to any of the 6 email lists on all 6 sites. Can someone tell me how to do this? BTW, we are hosting providers and not DNN developers so module customization isn't an option.
Thanks, John
