Announcements: one more minor tip

I've seen that the announcements have not a date, eg:

http://community.invisionpower.com/forum-1/announcement-30-what-new-in-ips-social-suite-40/

so when I go and read it I don't know when the author posted it.

I suggest a "required date field" for the announcements to be published

kind regards, Gianpiero
