How do you notify users when you need to take Bamboo down for maintenance?

Question

I want to email my Bamboo users when the server is being taken down for maintenance, but I don't see any built-in way to do this. It would be tedious and time consuming to try and copy all of their addresses into an external mail program.

Does anyone have a creative solution?

This is pretty creative if you're on Unix:

for i in $(seq 0 25 200); do
   curl --user user:pass "http://bamboo/admin/user/viewUsers.action?startIndex=$i";
done | grep @ | grep -v \" |xargs mail -s "Bamboo Server is going down in 10 minutes"

You can also write a plugin that does it. Accessing Bamboo User database  and mail service in a plugin is quite easy. I don't think it would take more than 10-15 lines of Java code to do this.
