Hi Mike, Thanks for the responses. You mentioned earlier in the thread I could use mmr.pl to initialize (only) a consumer. I don't see that option with the tool; only "create", "remove" and "display". I noticed the create function calls three other functions, "config_supplier", "add_rep_agreement", and then "initialize". If I want to initialize only, do I need to re-create the agreements? I tried modifying it to have an --init option with only the "initialize($host1, $host2) function being called, but kept getting the mmr usage, and wasn't sure if its possible to do an initialize only.
