Hi,

Depending on what you wanted to do with the forms when you've found them, you could just treat them the same way as any other piece of content. Rather than using IFormRepository, you could perhaps get all instances of "FormContainerBlock" and filter them by creator (which is a property of IChangeTrackable) like this:

var contentModelUsage = ServiceLocator.Current.GetInstance<IContentModelUsage>();
var contentTypeRepo = ServiceLocator.Current.GetInstance<IContentTypeRepository>();
var templateType = contentTypeRepo.Load("FormContainerBlock");

var allForms = contentModelUsage.ListContentOfContentType(templateType).Select(x => contentLoader.Get<IContentData>(x.ContentLink, new CultureInfo(x.LanguageBranch)));
var bobsForms = allForms.Where(x => (x as IChangeTrackable).CreatedBy.Equals("Bob"));
