E-science Gateways are the primary solutions dedicated to support end-users without
grid knowledge to do their research on distributed grid infrastructure. Due to the
wide range of research fields, generic grid workflow management systems/portal
services should be flexible enough to support the different requirements both at
front-end and back-end side. Previously the importance of science gateways was
overlooked. This required a huge (time and skill) overhead in usage and development
due to the required complete understanding of various distributed infrastructure
technologies and solutions. As a result adoption of these e-infrastructures has been
below expectation until today. Recognizing the problem many attempts have been made
to create user/community-specific and user-friendly science gateways for the various
e-science communities. In this oral presentation we introduce the newly developed
features of gUSE a Grid User Support Environment and the WS-PGRADE portal solutions.
