[xwiki-users] where put macros?

Hello, Where is the best space to put macros? I check in some macro from code.xwiki.org, and find that macros are commonly put in XWiki, Macros or Macro space. I've a preference for Macros as it self explanatory and I think XWiki space more dedicated to XE pages. What do you think? Regards, Arnaud.
