I've created some templates on English Wikipedia to help Advogato members to network there.
Put something like this on your user page:
Replace minorityreport by your own username. advogato-0 is observer, advogato-1 is apprentice, advogato-2 is journeyer, advogato-3 is master. If you want to be coy, use advogato without any number, and we'll just have to tramp on over to Advogato to tell your certification level.
Whether or not you use them, please feel free to say hello at my Wikipedia talk page.
