I have answered you previously that it takes time for your message limit to reset. Though I have never hit it personally, I've seen others take up to a day. Be patient. Rapidly emailing Pet after we, or he, gives you answers is not advised.
Isn't petrarca the administrator of the site? If so he's very busy. That's why you should turn to moderators for answers. He doesn't always answer them according to his profile. And if your limit was reached how can you talk in the forums. If it doesn't reset then that means a moderator gagged you.
You message limit does not affect your posting, I know lots of people who can message in the forums while their message limit is being reseted. As well, moderators can not force reset the messaging system, only the admin has the ability to do that, but as Awake has said, he has told this shh.... already.
