I want a social site in joomla or php so that members can enter their articles and have it published right away, the title should be linked to a source that the member gives, like their site or blog. I want limitations in the submission form, in the amount of characters and no images, I also want to have filtering options, such as highest hits, rating…This is very urgent and my suggestion is joomla.Details:
-I want to make a site in Joomla so that viewers can become members. Activation should be without the confirmation of the administrator
-I want members to be able to enter their notes as a title and a few lines, so that the title is linked to the source of their own blog or site.
-I don't want them to be able to enter images, and the text should be limited to about 500 characters
-I want a feature that with clicking on the members name, you can see the members' others entries. 
-the members' entries should be published on submission,
-viewers who aren't registered should be able to see all the entries and comments
-I want a rating feature and hits feature for the entries
-the pages and links will be given later
