Are "Press Releases" copyrighted? or i just can copy some press release from other websites and paste on my website?
Copyright can be very complex, but many clips are available for distribution as long as you quote the source. Check before you 'just lift it off ' a page and 'drag' it on to your page We find playing by the rules is the way, frustrating as it can be sometimes, but it will bring in benefits that will give you job satisfaction and hopefully it can be fun too
Make sure it's really a press release. Get your releases from a source that releases them and not a 3rd party site. If you are going to rewrite, use the facts, but don't copy any creative elements.
There are plenty of them posted at DP. The same places where people can submit press releases, allow people retrieve them, this is just one of those posts but using the search function on the top you can find many others: http://forums.digitalpoint.com/showthread.php?t=119295
