Get rid of back-to-front dates Posted by Cri de Coeur to Settings, 29 Apr 09 at 11:20
Why does this otherwise excellent email service insist on using these screwed-up, back-to-front dates with days months and years organized in no recognizable form of logic or progression. At least give people the option to set their interface to the standard dd/mm/yy format; and a nice bonus would be the option to adopt the ISO yyyy/mm/dd format which is so useful for archiving. You do set out to be an international service, so please, please get up to speed on this one. [....]

Share 5Gb Webmail Storage across File Storage Posted by bradavon to File Storage, 1 Apr 09 at 15:58
Are there any plans to share the 5Gb across Webmail and Webspace? Instead of the current 1Gb shared limit. The 1Gb limit is restrictive.

Otherwise, simply increasing Webspace to match would be even better. [....]

Tighter intigration of the mail and calendar functions Posted by Tuxedup to Organizer, 9 May 09 at 20:13
I would like to see tighter integration of the mail and calendar functions of the gmx service. Some initial ideas are;

Make the calender system intigrated with mail. For example I would like to see that when a date is found within a message, than right clicking on the date gives the option for 'add this date to calendar'. At which point a box opens allowing you to add the date to the calendar with information such as location, description etc.
