This idea is for the Vocaloid wiki.
On the wiki we have a song listings page. This page is for contributors to post links from YouTube to make them easier to find for people who don't want to bother with filter searching. I plan to revamp the way this is done by adding more listings (not just YouTube) and creating a template that will cut the need of posting the whole URL. So the template will only require the video's id number. Going by how the pages are currently done, the template will be in use a lot on one page. I wanted to know if a templates multiple use on one page has an effect on the wikis loading and does it effect various browsers.
