On our blog/site I have created a page for announcements. 

Find the page here. Check it regularly as a noticeboard. 

I have put two notices there already. If you have comments or questions about any of the announcements, leave them as blog comments there. Unless it's a sensitive issue.You be the judge.

Please if you have announcements with details that members need to remember, gain access to the blog and share it there to serve as a reminder.
