Due to an unexpected server problem, any changes you may have made to your member profile, including passwords, contact information, and so on, reverted yesterday evening (Wed, Apr 26) to what it was like roughly a day prior. If you made any changes to these during this time window, you'll need to re-do them.
This may also mean post counts were reverted to a day prior.
(The technical info, for those interested, is that the "members" database table in our database forum became unexpectedly corrupted, and that table only was restored from a backup from the day before. Also, this was connected to the downtime last night--it was the restore that brought it back up.)
