Well, some phrases (and yes, phrasal verbs) get concatenated over time, like "understand", "overtake", "courtmarshal", "becalm", "whipsaw", etc. The conjugation and number rules work themselves out eventually, for example, "courts-marshal", "overtook".
It's just one of the ways languages mutate. Usually the noun form mutates first, and later on the verb form, but not always.

The point is that phrasal verbs are written spaced: "stand up" -- even when conjugated: "stood up", not "*standupped".

Following the model of "understand" -- I'm going to start going with "inlog". Inlogging, inlogged, inlogs -- it just works!
Go get 'em, tiger.
