Alchemywiki
I added as a proof of concept possibility to link 2 result elements instead of only one.
(Trick is to add extra tag to page "hastwo"). This will trigger iftag statements and allow linking of extra element.
Test page is "1UP + Mario = Mario + Mario"
Extra element i entered in Second Result Element field.
I manage to edit all pages except for list of combinations page which is locked so this one needs to be corrected.
Same mechanism can be used to add support for up to 4 result elements.
This could allow us fans to add all known combinations to this wiki.
(Kudos to site administrator for clever way of using wiki functionalities to produce this site)
