Redmine

Hi,

I search a solution to add custom fields in news module :
- a (forced) custom field for the organisationnal unit they are ( free text, or from a list of values )
- a custom field for any tags ( free field, themes of their news )

Tracker personnalized fields cannot be used.. so :
- i have to fork/rewrite the news module in a another module ?
- any idea of a plugin able to do that ?

Thanks by advance for any clue

PS : Redmine version not chosen yet, maybe the last one. Users will be authentificated by LDAP.
