Why do people constantly change the title of discussion threads. The makes it very difficult to follow the thread via the 'posts in the last 24 Hrs' button at the bottom of the front screen.
Surely, if your comments are not relevant to the title you should start another thread. Thread titles are surely chosen by the originator of the thread to identify what
they want to talk about.
From the Site FAQ's
Why is a post's subject so important?
The first post of a given thread establishes the subject by which all subsequent replies will be known. Once there's been a reply, the thread subject cannot be subsequently changed. It's therefore important to get the subject right from the outset. Make it as descriptive and as specific as possible. For example, 'LCD burn-in questions', is much better than something completely generic, such as 'Newbie needs help!'. Not only is it more likely to elicit a response, but it'll also make it much easier for all posts in the thread to be subsequently located.
