Today I fixed e-mail notifications about events - like new posts, private messages etc, so everyone can again be more in touch with us

E-mail notification settings can be controlled via User Control Panel.

I urge everyone to update their e-mail address in account settings here: ucp.php?i=profile&mode=reg_details

There are a lot of folks who have an old e-mail address there, so they can't receive notifications. That's why it's important to always have current address in profile.
