You can manage templates using Recite WebDAV, however this is limited only to editing and deleting existing templates. That is, you cannot create new templates. The reason for this is that the type of a template must be defined prior to its creation, and this is not possible using WebDAV.
Most text editors provide an "auto-backup" feature which saves your data automatically as you are working. If your editor is set to save backups to the templates directory an error will occur, since Recite is designed so new templates must first be created using the Control Panel. Either disable this functionality or if you can, change the location where backups are saved.
Furthermore, some text editors (such as jEdit) optionally use a "two-stage save process" as a workaround to some unix-related permissions issues. You must disable this feature when editing templates stored in Recite, since this will cause an error for the same reason as in the previous paragraph.
