Apply template without removing contents?
When editing a wiki page, if a template is applied, existing contents will be deleted. Is there a way to change it so a new template could be appended without overwriting exsisting contents? This could be helpful in these cases: 1) A user didn't apply a template when creating the page, but later on (or sb else) can easily apply the template to it. 2)Apply multiple templates to a single page.
Is it relatively easy to hack? Thanks.
