Character Limitation of Event Short Description

Hi Tuan,

as event owner i can type in some text for short an long description of every event.

Most of our users only use the short description and type in all the text in that field (short_description). How can i limit the output in frontend that e.g. on ?task=view_category you only can see the first 300 characters and a link "read more" which will link to the event details with long description?

For now, the short description will destroy the layout of the category overview.

Thanks,
Matthia
