If you are wanting to give your departments a unique look and feel by using different colors and logos for each department, you can achieve this by creating multiple layouts. An example of this is making your Music Teams design different to your Kids Team design. These days a lot of churches have their own logos for each of their departments.
To create a new layout, simply navigate to Settings and once the page loads, click Layouts.
Each layout has its own subdomain so for your people, it is like they are accessing their account from a totally different website. However, all the data is still pulled from your single Tithe.ly ChMS account. This way you can manage multiple department websites from the one account.
You can customize the look and feel of each layout, using the instructions in this article.
