To most easily find new hooks for creating a new box, go to Wikipedia:Recent additions and search for "volc". For finding older hooks, you can use this Toolserver search. Newly added series go after the highest-numbered current one. Do not change DYKs from their Main Page appearance. Also, don't forget to update the "max=" parameter for the section on the Portal page.
