Mike, an excellent initiative! The rulebook currently recognizes competitions consisting of any combination of the three powerlifts plus the military bench press. This implies that rankings are kept for these lifts. I have also envisioned the odd "special event" in other lifts. These would be more informal with no rankings or meticulously written rules.
That said, if there is enough interest in regular competitions with rankings etc. in other disciplines than pure powerlifting I am all for it. I have begun building up a backend to automate much of the routine tasks involved in running global multi-lingual Internet-based competitions and this framework could be put to good use in other events as well. Having them under the same roof would also create synergy in terms of achieving broad attention that would be beneficial for all events. However, these events must be arranged IN ADDITION to the regular powerlifting meets. In short, if there are people who are willing to write the rules, moderate a related forum and take care of running the events, then I'll gladly provide the server and software resources for it. Naturally, these events would need to be drug-free, open to both sexes and have free entry.
...so those of you interested in other events, whether a tactical strength challenge, crossfit total, strongman, weightlifting or something else, please gather your forces and work out the details.
This thread is an excellent point of departure, but I'll be happy to open up a forum when you are ready to make a serious push and need a venue for working on it.
