Hello, I know this has been asked before, but I'm running into the "MKACTIVITY...403 Forbidden" error when I try to commit a file. A previous response to a similar query in this message list said that you need a developer account (which I'm pretty sure I have; I've created an account with SVNManager) not just a Trac account. Okay, assuming my developer account is hunky-dory, I guess the next step, according to http://svn.boost.org/trac/boost/wiki/BoostSubversion, would be to invoke svn switch --relocate http://svn.boost.org/svn/boost https://svn.boost.org/svn/boost/ your-username/ --username Well, that would be great, but svn.exe isn't installed with Tortoise SVN, so if that's what I need to do I can't do it with just my TortoiseSVN installation. So... Is running svn switch what I really need to do? If so, do I have to download a separate installation of SVN? (That seems redundant, as TortoiseSVN appears to incorporate the functionality of SVN in one of its executables.) How can I commit my changes successfully and not get the Forbidden 403 message? Thanks, Phil
