I find that on every topic I create has a subject that is too big. While this is really more of a minor annoyance since I don't create topics too often, it would be nice if the MAXLENGTH property for the input box was used to let the browser stop you from typing once the limit has been reached.
Besides that, longer subjects would be appreciated. The more descriptive the subject is, the easier it is for people to determine the jist of the thread and whether they want to read it or not.
