First sentence: 'there' should be 'their'
Second sentence: comma after 'art should be a colon.
Also delete 'from'.
Also 'Photos' and 'Videos' shouldn't have caps.
First Rule: 'anyones' needs an apostrophe; (should be anyone's).
Second rule: 'Libelous' should be 'libellous'
Last rule: 'there' should be 'they are' (or 'they're'). Also 'provided that' would be better than 'as long as.'
Under 'Artists': 'Video' shouldn't have a cap.
Under 'Submit Work':'setup' should be two words. Also fullstop after 'like this' should be a colon.
Lastly: 'Msn' should be all caps.
Hope this helps.
