Can't edit Joomla K2 pages/posts

I'm having trouble trying to edit posts or pages made in the Articles/Joomla K2 Engine. I can sign in but can't find any way to reach a dashboard or whatever it is that that platform uses.

Yes some sites don't have a link to it...by default it is...

/?option=com_users&view=profile&layout=edit
