Under the user summaries accessible to admins, the account creation timestamp is recorded:
Users > Activity > Created
For me, it would be helpful if the account application timestamp was also displayed:
Users > Activity > Applied
I know the overall application and approval process is currently being revisited. Perhaps my suggestion can be considered as part of that exercise?
Added material
Perhaps I should provide some more context. The forum I admin uses application screening and sets new users to trust level TL2. We now increasingly get both en‑masse generated applications and user statements written by AI. The former often has a uniformity, while the latter is invariably vague and clichéd. As a result, the tracking of applications is becoming more involved, hence the usefulness of having an Applied timestamp for cross-referencing purposes.
