Yes, there is, and you can sign up here. The demo/trial period is 14 days
You can use demo data, or start with a blank database and add your own records. Demo accounts come with all ChMeetings features, except custom elements: sender name and reply-to email, form attachments, custom profile fields, and the church URL. You also cannot communicate or run automated tasks with a demo account.
At the end of the trial period, you can sign up for a permanent plan and either keep the data in your demo account or remove it. Permanent accounts start free and come at affordable prices. Check them out here.
