General point on SVn access, since several people have requested it recently, I wanted to clarify the position.
Anyone can use it to read the latest version and play it.
Only modders get write access to change it. Since it's Strategyonly's mod, I only add people when he gives me the ok to do so. In general, we normally ask people to initially make contributions by submitting changes through one of the existing modders, whichever is mostly working in the relevant area, or to make a modular mod mod containing their ideas. After a probationary period like this SO makes the decision to promote people to core modder status and give them direct write access to the SVN.
In terms of who is best to submit your changes through initially (if you don't want to go the modular mod mod route), it best to start a thread about what you intend to do and ask who you should submit through once the ideas have been talked over a bit.
