Just so you know, you can always check if the creator of an alien is still active by clicking on the arrow next to 'Edit', then selecting 'History' from the list that pops up. Scroll to the earliest listed edit to find out who made it and click on their userpage. If they don't have an 'Inactive' icon next to their username, then they're probably still around to ask permission from.

Of course, you could just skip that whole process and choose from our Free Usage selection of aliens and what not, which don't require permission to use.
