the dark theme I have been working on is pretty much complete (apart from a few minor tweaks I intend on making to fine tune it).
you can select it if you don't want to use the default theme by going to profile > account settings > modify profile > look & layout.
after selecting this theme, you might encounter a page here and there that has either not been affected by the theme change, or has been rendered incorrectly.
if you come across a page that still has the default theme styling while the dark theme is selected, post a reply to this thread containing the link to the page in question, as well as a screenshot if possible, and include the browser you are using so I can try to replicate the issue with a view to fixing it.
feedback welcome, I will keep suggestions in mind while I am fine tuning it.
