Unlimitedapps Here is xtgem Forum Twig tutorial: ADVANCED USERS ONLY
Xtgem uses twig templates to create the markup of forum blog and guestbook
Twig is a php template engine the documentation for the template development tools is available at
http://twig.sensiolabs.org/doc/templates.html
You do not need a php upgrade to use these twig files
First create a folder named _xtgem_templates in the main file browser (root)
this folder is where xtgem expects to find the main twig files
Note: to allow the use of "upload by remote server" most of the files have a .js extension this should be removed after upload
Do not edit twig files with the building tool you must use the code editor
FORUM

http://syntax.xtgem.com/_templates/xtforum.twig.js

http://syntax.xtgem.com/_templates/my_blocks.twig.js
both are required
