The bulk update request #11470 is pending approval.

create alias teleport (57) -> teleportation (350)
create alias teleporting (0) -> teleportation (350)

Reason: These are effectively identical.

teleport currently has several active tags: https://e621.net/posts?tags=teleport
teleporting is not tagged currently, but has a history of being tagged a few times: https://e621.net/post_versions?commit=Search&search%5Btags_added%5D=teleporting - I figure there's no harm in aliasing the verb version to the noun.

If this tag is deemed too ambiguous or not worthwhile, then adding aliases now won't impact a disambiguation or category change later.
