We require the ability to use numbers in our JIRA project keys.
However looking at the documentation it says that any change to the default project key format should be avoided as Greenhopper only supports the default (at least two upper case letters).

All I want to do is allow numbers and not any other characters like dots or dashes which are more likely to break Greenhopper so I was wondering if anyone has changed the key format to use numbers (maybe something like ([A-Z][A-Z0-9]+)) and not had an issues with Greenhopper?
