What are the best practices for assigning and rendering variables in a template file within the wbb2 forum framework?

When assigning and rendering variables in a template file within the wbb2 forum framework, it is best practice to use the template engine provided by the framework to ensure proper separation of logic and presentation. This can help make the code more maintainable and easier to read. To assign a variable in a template file, use the `{assign}` tag provided by the template engine. To render a variable in the template file, use the `{$variable}` syntax.

// Assigning a variable in a template file
{assign var="myVariable" value="Hello, World!"}

// Rendering the variable in the template file
{$myVariable}
