Thanks to Fab and the guys in #morphos IRC, I've sorted my earlier issues with my 3.0 install. Network performance seems to have improved a lot since I manually configured IP/DNS settings, it's pretty respectable now, seems there is something about auto DHCP on my router it didn't get along with.

My issues with Wookiechat were solved by deleting and disabling it's logging output.

Thoroughly enjoying using 3.0 daily now!
