Not a problem, you're doing a good job as it is. Mostly I'm just worried you might jump to v6.1 'only' once that's released before supporting multiple threads under 6.04/6.05.
While lots of people have flexible forums, I couldn't take the hours of hacking and private customization to install 6.1 =).
Note that v6.1 will be BETA to start with, but its got some big differances in the way it handles and indexes posts.
