Does anyone know of an announcement plugin in which you can set start time, and time and interval but all through In game commands and for multiple announcements? A command might look like /announce (message) (interval) (start date) (end date)
There is one simply announcer that you can change your announcer name and your messages. You may also change your announce interval. You can find it here.
All announce plugins do this lol... I vouch for ScheduledAnnouncer2, it's very well done and it runs very smooth on my server.
