Just a quick post to point you to a site that you might not know about: openCollabNet. This is a site being hosted and supported by CollabNet to provide an online community for Subversion and CollabNet users.
It is a pretty cool site that seems to have a lot of information contained within it such as articles, forums, podcasts etc. I will probably start compiling a list of interesting links and add them to a new post in the future, but for now I would suggest you poke around the various parts of the site and you will likely find something useful.
One of the more immediate things you might find interesting on this site is that they are providing binaries for various Subversion components and tools (such as TortoiseSVN and Subclipse) and I believe they will provide support for those binaries. Currently, I think they are only offering Windows binaries. I would really like to see them provide some for OS X as there currently are not any good sources for up to date binaries for OS X. Metissian used to provide a very nice package, but they seem to have stopped providing them. Not many user's are going to want to download and install XCode so that they can build Subversion from source, and many that do seem to run into problems with various parts of the process -- at least those that are building JavaHL. Anyway, hopefully they have OS X support on their to-do list. Linux binaries would also be nice, but at the same time I think the Linux distributions are doing a decent job providing Subversion packages that work properly, so it is slightly less urgent when compared to OS X.
