Hi,
I'm not sure if I'm the only one, but frequently, when I am writing a long post, Kunena frequently drops the connection. Sometimes, I am able to put a post through after 2-3 attempts to try again, but sometimes, it simply will not work and I have to post again. It's at the point where I write my forum posts in a text editor and then copy the results over, so I don't lose all my work. In case it matters, I use Firefox and it seems to be device-independent. Some upgrades to Kunena's robustness for posting would be welcome.
