Just noticed that, when merging users during an import, the merged account uses the newest registration date rather than the oldest. For right now, with imports from 3.8 where you have maybe two to three at most users to be merged from the initial setup and testing, it's simply enough to go into the database and change the registration date to the date in the old database. However, I can forsee big problems down the road for communities that want to merge together. The registration date is very important in regards to the awarding of a number of custom trophy point awards (days since registration comes to mind). Not sure if this was the intended design, but it seems incorrect, hence the bug report.
