Flyspray - The bug killer!

Hello Peter,

I am interested in making the following mod:

When posting a new task, category should be blank by default, in order for the user that opens a new task to select that specific category.
If he doesn’t select any task, when pressing Add this task button, FlySpray should display an error message saying that the Category hasn’t been specified.

Do you think this mod can be made with the current version?
If so, do you mind if you help me a bit with the things that need to be modified?

Thanks!

Steps done to create the problem:
Visit https://bugs.flyspray.org/index.php?do=register in a private browser window (so you are logged out)

Put in an already taken username (e.g. Stefan or Stefan2)

Expected behavior:
Username gets red and a note appears that username already is taken

Experienced behavior:
Username gets green and registration of a new user proceeds with sending a notification mail with confirmation code.
After putting in the confirmation code in provided page, user gets presented a “username is already taken, choose another” (where?) message, and has to re-start registration process from beginning and hopefully this time choose a not taken name.

I unchecked the avatar allowed in the admin panel. I checked it back and set size to 50.
I have to upload an Avatar picture to restore it, but the previous avatar looked like to be html avatar.

Is there a way to restore the html one ?

note: ‘default avatar’ is currently just that guy from the fontawesome webfonts:

<i class="fa fa-user"></i>

The current jscalendar shows sunday as the first day of the week by default.

Could be modified for a language by adding

// First day of the week. 0 means Sunday, 1 means Monday
Calendar._FD = 1;

js/jscalendar/lang/calendar-XX.js

It should default to Monday as defined by ISO 8601.

Short dates in Greek are represented in the majority of cases with slashes (24/10/2016). Very seldom some people may use the dash form (24-10-2016) and hardly ever the dot form (24.10.2016).

So it would be much appreciated if the slash form were a (working) option because as it is dates are a bit confusing to us, especially in a date-time combination (too many numbers in a not-so-obvious format - brain needs extra time to decode it).

I prepared Slovenian translation.
