It's broke

I can't help but feel that almost 50% of posts on this forum are extremely unhelpful.
And no doubt ill get some flaming for posting this reply too.

As for the frame breakage I would either get it repaired or get a new frame.
The fact that the frame has snapped in that place could indicate that it will snap in other places too due to age.

Well, if you're going to say something like that, you should at least make a useful comment yourself! :) Saying 'get it repaired or get a new frame' doesn't make it useful, you should have included framebuilders/cheap places to get replacement frames. :)
