Wow. You never made an event before right? depending on the scale of the event posting it once per thread till the event proper is good. This ensures the event will go ahead smoothly.

Think of reminders as a logarithmic curve. You post reminders more frequently as the event arrives.
An event a month away will be okay with reminders every week for the first 2 weeks. Then when the event is 2 weeks away a reminder every 3 days.
When the event is 7 days away, a reminder every 2 days.
When the event is 4 days away, a reminder every thread.
Then when it is the day of the event a reminder every on that day's thread and one an hour before the event and finally 15 minutes before the event telling everyone to log in.

Logarithmic posting makes sure that everyone catches wind of it without being over bearing in post count.
