As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.
1) Oops. Forgot about this issue; https://issues.alfresco.com/jira/browse/ETHREEOH-2804. You'll need to change the RSS feed URL to use the webscript in /alfresco rather than try and proxy it via Share to get this to work.
2) Modify login.jsp and change the URL, which is hardcoded to the user dashboard.
… <input type="hidden" id="returl" name="returl" value="<%=request.getParameter("returl")%>" /> …
That is actually the wrong file, the URL is hardcoded in site-index.jsp.
response.sendRedirect(request.getContextPath() + "/page/user/" + URLEncoder.encode(userid) + "/dashboard");
