Can I use CoffeeCup forms on multiple URLS or do I have to have to purchase a separate account for each web client? I have a couple different clients for whom I'd like to be able to create forms (easily) and publish on their website. So far it looks like I can only have one URL at a time even though I purchased the full program. Your help would be very much appreciated. Thank you.

Hi Maddi,
You can create/publish as many forms as you want. When you make a form, go to Settings and enter the info for whatever website the form will be used on. Save it and export it to embed it on the client's site.
If you want to use the same form design on different sites, just save a copy under a different name and change the settings info.
If you're using SDrive, you'll have a limited number of forms you can publish on your account, but that doesn't effect what you do on your clients' sites (unless they're using SDrive, too).

About your general licensing question, Coffee Cup (so far, anyway) licenses and supports the Web development tools it sells (http://www.coffeecup.com/software/) on a per-user basis. The user (you, for instance) can apply those tools to whatever projects you desire at no additional cost. This simple model seems to work well for CC and its customers. IMHO, this policy has encouraged growth of CC's useful and forthcoming user community.

CC also provides services (http://www.coffeecup.com/sdrive/) by paid subscription. Their use is somewhat restricted, as paintbrush points out with regard to SDrive.
