What is the best forum software for me ?

[محروم.كوم]

Hi
I am using phpBB2 with 2300 users
I was okay for a while with that forum... I want to change and update... not sure I do like the phpBB3 tough, so I did a little search. Even tough I am using Wordpress on my article side of site, I am not sure that bbPress is the best choice for me

What forum would be a good choice for
- 2300 user
- french or english
- send PM
- RSS
- Forums and sub-forums
- need to be able to "embed" a youtube video when members are posting
- Profiles

- Avatars and signatures

I use this to try to help me
