#1 - The ability to stay logged in. This is still broken. Why? Is it really that difficult to fix?
#2 - The ability to be able to choose to be notified of replies instead of having to uncheck the box each and every time we post. Very annoying. It should be the opposite. Check the box to be notified of replies. I don't need to be sent e-mails from every thread I have posted is so it's odd that it's defaulted to "on". We even have to uncheck it again if we go in and edit a typo.
#3 - A better, more readable color scheme. Darker text on a brighter background is always easier to read that brighter text on a dark background, even on computer monitors. But that's not my main complaint. There are lots of links and text which are very similar in color to the background. And odd stylistic choice.
If there are behind-the-scenes reasons as to why the forum is still broken, please let us know. Don't just sit there in the shadows and let us wonder if you're still alive. If running the forum is too much for you, please find someone else who can as a lot of people really value the forums, myself included. Also I'd highly HIGHLY recommend going with different forum software than Kunena Forum. There's plenty of free BB software out there that is far superior. phpBB and Simple Machines are two good examples and you can choose from a variety of different styles and adjust the color schemes yourself.
