I suggest adding to the account login page text listing any warnings that have been added to the account. Specifically, include:
- Date of warning
- Name of GM applying the warning
- Character on the account involved
- What the warning was for (and whether it's a last warning)
There have been a few cases where players in the Account Issues forum were banned and said they didn't receive a warning. But they had, only it was many months prior. Since warnings stay on an account for the life of the account, then this can serve as a reminder, and maybe avoid GMs having to handle ban appeals from a player who just doesn't remember he was warned about something. Also, it will serve as a caution to follow the TOU if it prominently appears.
Also it would be useful to show on that login page the last IP address that the account was logged in with. This may help players determine whether someone has accessed the account other than themselves.
