Hi There
We are considering trying & using the Issue Collector to enforce a policy, so as to compell users to enter a few set of information in some tickets for a project, without having to modify anyhow the attributes in the JIRA project, so as to keep it very simple. It means, in the issue collector, people would be possibly asked to enter a few fields, some of them being defined in lists of values, some being text fields, and in the end, when submitted, the jira ticket created would gather these pieces of information in the description.
Have some of you tried this? Any particular opinion about this? Again, of course, I know we could add attributes to this project, but we want to avoid that, as we try & keep all our JIRA projects standard, to make maintenance/upgrades easier 
Thanks for your help
