function isMainPost(tid, pid, callback) {
RDB.lrange('tid:' + tid + ':posts', 0, 0, function(err, pids) {
if(err) {
return callback(err, null);
}
callback(null, pids[0] === pid);
});
}

Kool, looks like there is already a function PostTools.isMain to do that after further investigation. Will see what i can do with that.

Was looking at writing a plugin that adds additional data to the first post. like say a topic status mabye (availabiity/sold out). Would it be best to put that as a topic field item? or post field on the first post? If topic, i think there would need to be additional plugin hooks. if first post, is there an attribute to a post that is passed to the plugin hooks that it is the first? I didn't see one when depuging out the postData

Would be great to see a skeleton of a plugin that supports parameterized (/someplugin/:someid) urls as well as dynamic templates.
