I was trying to make some factbooks for my region, and I gotta say, that formatting is extremely dysfunctional. I was using this dispatch as a reference https://www.nationstates.net/page=dispatch/id=330837.
Tables are nice, but the mobile version of the site completely butchers them. Tables themselves don't seem to have an option to set the width of columns manually, they are automatically sized to their content... Needless to say that this sometimes leads to undesirable results. Image placement: most sites allow resizing images placed using BBcode. Not Nationstates. It gets even worse when images are placed inside tables, as they get arbitrarily resized. When viewed on the mobile version, the images always seem to appear in full size when they are placed in tables. It is possible to put text between two images on the left and right-hand sides. It does not seem possible to put a table between images in a similar fashion. Scaling of various texts and images with different screen resolutions also seems to be off, what appears to be a neatly packaged text with images beside it will appear as a convoluted mess with another resolution. Not sure if it can be fixed, though. Either way, more customization options, especially regarding image sizes and placement, and improvement of how the mobile version handles tables would be much appreciated.
