MyBB Community Forums

I'm just wondering can you put a mybb forum on your wordpress thesis theme. I have seen lots of blogs around using forums but id rather use mybb to be honest.
Anyone have any help?

If it's just a theme then yes you can easily edit the templates and css. If it adds php and other stuff then it will get a lot more complicated.

I only hope you aren't going to use an unstable, beta version of MyBB...

Being honest I'm only new to all this jazz and its my first proper website so I'm want to do every thing the right way. So what would the proper way be of going about adding a forum to my Wordpress Thesis Theme?

Probably make the theme using 1.4 and update it or wait for 1.6 final.
