Handling multiple sites?

[Talryn]

I hope it's not an issue asking this question here but I think I have to ask it somewhere.

I'm curious how some of the prolific add-on authors handle adding and updating their add-ons on the multiple sites. I've liked and used wowace.com and wowinterface.com for a long time.

I would think it would be painful to use version control at both. Is there a recommended way to handle it? Is it best to use version control at one or the other and then just post the file at the other one? If so, which site do you use?

Thanks!
