At the kind suggestion of +Jacob Possin
, I'm sharing a Google Form to collect additional Aspects for the Random Cluster Generator. The form asks for the Aspect Phrase, the T/E/R levels for which it might be appropriate (including "don't care"), and a contributor credit.
No promises I'll add your contribution, but if so, I'll add your name, handle, etc. as a contributor to an updated edition.
You are of course free to make a copy of the Random Cluster Generator and add your own Aspects. To support this, it's a single page without dependencies here: http://www.aristobit.com/diaspora/randomcluster.html
