Now a daily email is sent resuming all projects changes (only if there is any).
A team feature I should have done long time ago. So we don't have to go on the site to be alerted about other team members progress. I think it is stimulating.
I have corrected another stupid implementation. Hidden projects ("active" or not) were hidden for all the project members as soon as one decided to hide it from the project list. Now each user can decide to keep it on its list or not. But I didn't keep the current hidding settings, so all hidding status are reset.
