Click in his nick and ---> "Start a Conversation"
You can open a thread in this subforum (for XMB modding), there is some other people in the forum that knows a bit how it works
It seems you are mostly focused in animations, there are some pages in wiki related with other rco stuff, but im going to mention a couple related
This is the xml code generated by rcomage, is a list with all the available "construction blocks" for animations
http://www.psdevwiki.com/ps3/RCOXML_Animations
And this is intended as a training to understand how the official animations works, the goal of the page is limited to only official animations, i wrote it trying to explain it in detail and we can talk about them as much we want, but thats all... "official only"

For custom animations my plan was to make more wiki pages with this style:
http://www.psdevwiki.com/ps3/XMBML_Coding_Examples (just an example)
http://www.psdevwiki.com/ps3/RCOXML_Examples (here can be added more wiki pages)
Im posting all this incase it helps you, or you want to collaborate, or there is someone reading us interested in this
If someone starts talking about this i will join the conversations and i will help in some way, giving you some hint or updating wiki
