@SYnapse: Your point seems to be off-topic, but the mods are there to prevent cheaters. A gunboat game is a game without messaging. Thus, using features of the site like pauses, cancels, etc. to get around that and message other players is a form of cheating, and as a result the mods are tasked with preventing it from happening. That's why the rules say "Don't work around game messaging/press rules."
@Draugnar: I'd rather not be too specific, except that I'm not talking about actions which would get around messaging rules or anything similar, but rather I truly do mean resources. As an example of a resource that would clearly be allowed, I can set up the game position on my own Diplomacy board and try moving pieces around, if that's something which helps me analyze the game. My question is whether there are some resources which are prohibited, or whether I'm allowed to use anything at my disposal apart from things that would end up being meta-gaming, getting around messaging rules, etc.
