* users will commonly realize they want to add a milestone when they're looking at some place where milestones are used: eg the milestones list, the bugs page, a particular bug
* if you need to have a series to create a milestone, just ask for it when creating the milestone
* in some cases people will need to also create a new series -- and this seems to lead into using one of the wizard-type popups described earlier this year
Overall I'd say this is a bit confusing, but it's also possible to learn how to use the current ui, therefore not a high priority. Maybe it can be considered in developing new UI patterns.
