1. I couldn't find anything, but thought I'd double check: do you offer any type of feed handler for TheFind, similar to what you have for Google Products?
Google feed is the only one that is integrated into ShopSite. I know that some other services accept the Google format so you might check if TheFind does. If they have their own format and will accept a tab delimited feed you could create a custom download format on the > Utilities > Database >Download > Products screen using the "Use field map" option to format the data as they want it.
2. For Google Products: For multiple stores, do you need to create a second account for the new store, or do you just create a new feed and append to the current account?
Since google verifies the urls submitted in a feed you will need different accounts for each store. You would need to check with google to see if they have a way that you can submit multiple feeds under a single Google account.
3. On the Shopsite Google Products configuration, I don't see a place to add some of Google fields, i.e. color, new/used, sale price, category, etc.
The latest version of ShopSite (11sp1r2) has all the fields that were required by Google at the time that version was released. So upgrading to the latest version would be your best option. You can also configure the extra product fields to map to Google attributes and add your attributes to those fields. You also need to check the boxes to use those extra product fields in the feed on the Merchandising > Google Services > Product Search > Configure area.
4. I recall reading that we can submit our store to the Shopsite store directory, but can't find this. Where do I go to do this?
Merchandising > Market Place
5. FYI: When I click "Click here to view support resources" on my Shopsite dashboard, it says the page is not found.
Where do you find this link? I don't see it in my dashboard area. When you right click on the link where does it say it will take you? Note some ISP's modify that screen so you might want to check with your host to see if they have modified the screen and added that link.
