Invitation reminders
It seems i’m always tweaking the invite process :) You can now send reminders to people who you have previously invited to join a team, but they have not yet joined. When you go to your team page, you’ll see their email address waiting for them to sign up. It has an envelope icon next to it. Click it and they’ll get a reminder email, along with the special signup code which joins them into your team.
PS - no news from Twitter yet :(
