You will notice a few differences between phpBB2 and today:
1. It's not Discourse.
2. Everyone must change their password at first login, just to freshen them up.
3. Reports are more private-like now, but we may get the old public reporting topic back later.
Known rough edges:
1. Styles may need more or less tweaks, especially the dark one.
2. Some BB codes are missing or/and need tweaking.
3. The only language available is English.
4. We'll know more when we find more of them.
