Hi.
I seem to be missing this.
Is there a way to have a default user for the project? I.E. - right now if a user creates a ticket but forgets to assign
it to someone on a dev. team. or select a category, nobody gets an email - it may be days before I get into the system
and see if there are any open tickets that are not assigned to anyone. Right now system doesn't notify me. One solution
would be to force selection of an Assigned To person, or another is to set a default person and category for issues
that didn't get assigned to anyone - so at least someone gets an email

possible solutions:
1) make field assigned to required
2) automatically prepopulate assigned to with a one of the member of the dev team.
3) make category mandatory and if the user doesn't assign a ticket to anyone on the team - it automatically goes to
that default category user.

Thank you
