Currently we have a local/testing server setup and we edit and modify files on that server via SAMBA. I just setup an SVN server and am wondering if there are any issues when having multiple users add to update repository from the same file system/set of files. We/I plan to use TortiseSVN as our client.

If I remember correctly with subversion if two or more users are editing the same file whom ever makes the commit first will update the repository and when the second,third,etc person attempts to commit subversion will warn them that a new version of the file exists and I believe you have a choice to update or merge the files. Subversions mainly used purpose is for development teams that would have multiple developers committing and changing many of the same files.
