Could I get you to look at this?
Fragment of a discussion from User talk:Rua
In the past I created entries for the three verb aspects, but I'm now thinking it wasn't such a good idea. It makes it impractical to list verbs because generally the aspects all combine into one verb in the descendant languages. Furthermore, some languages don't really have as many distinct classes anymore. For example, Germanic root verbs are something like 95% thematic verbs, but that doesn't mean their ancestors were. So it's better to keep them together on the same page.
