Just post, clock it, repeat. This is why a group is supposed to have more than one active member. You could try dig up Estro or Brutus' email address, send'm a PM, cover your bases and all that if you feel uneasy about activating the 72 hour rule.
The 761-hour rule
Just NPC their forces or something, but don't like, turn them into complete idiots at warfare. Y'know, make it reasonable. Logical.
Some one want to clue me in on the 72 hour rule?
The 72 hour rule applies to competative pvp-RP's. If the other side doesn't make a post within 72 hours after your last post, you can post again.
It isn't really enforced very much under the new rules, we like to give each other some leeway on these things because we can't always post. But eventually once we have been waiting for a few weeks we get a little bit bored and want to get it done (because generally one competitive fleet RP will affect other competitive fleet RPs).
