MaineOne:
On database issue, I was incorrect you should be able to change it useing VWD express. Goto the Database Explorer and right click on the table then select Open Table Definition.
If that does not work for you let me know if it even opens the definition view.
Thank you MaineOne you've solved all my problems I've changed varchar from 800 to max with vwd, now all works fine I was wrong because I tried to change this value in the property window of description instead of the "Events" table as you wrote.
If somebody is interested to this topic there is a simple way to bypass this problem
1)Add new event as administrator
2)write the heading
3)select link and Use a link instead of inline content for this anouncement putting the page name as link: youreventpage.aspx
4)write a short description for this event and save (in a new page you can copy and paste text without problems and you can create new pages simply by coping a page as "contact" rename it and adding your content in the content place holder)
maybe this way is better for indexing events and news in search engines
Thank you very much MaineOne
