Hi Michael, For the imminent release of the relax GUI, it would be good to soon modify the relax website (http://nmr-relax.com) to include information about this. For example the relax features page has a section at the bottom for the different UIs (http://www.nmr-relax.com/features.html). It also has a data visualisation section which could be expanded. But I would also include something on the front page http://www.nmr-relax.com/ in the 'The power of Python' section. I would add a second paragraph about the GUI, and maybe change the subtitle to "The multiple UIs and the power of Python". The API page http://www.nmr-relax.com/api/ will automatically be updated once the branch is merged into the 1.3 line and a new release is made. There may be other places that could be modified. Actually, ideally would be to create a new page called "The multiple UIs" and include lots of screenshots :) Regards, Edward
