what are your favourite subversion tips and tricks

Subversion is my source control of choice after experience with source safe and subversion. Developing with .net I find the commit dialog cluttered with files that are not relevant and should be ignored. Since v1.5, ignoring patterns of files and folders is a life saver to help prevent missing files that I should be checking in. Another tip I find useful is adding external assembly binaries with a "Latest" version folder: ``` Repo A - Proj1 - Lib(External retrieves latest binary of Repo B) Repo B (Library) - Proj1 - Proj2 - Binaries - v1 - Latest ``` That way, when I do an update, I get the latest external assemblies too. What tips and tricks do you have for making life with Subversion easier and as a developer?
