Could we have an adjustment to some parts of the theme here in the forums? perhaps a choice between 3-4 options? etc light, dark, sepia, light moss, blue.
when I go through the lists of topics I currently have to try and differentiate between black text (for something new) and grey text for something I have already visited, which is rather difficult on my worst days.
additionally, only having a light theme can make it harder to read the posts when the time starts to reach the later hours of the day and it begins to get dark.
