I thought I would see what others are using. I'm currently using Tortoise SVN, but it has no ability to search a repository, so am looking for something else. I am currently giving Sourcegear Vault a serious look as it's free for single use, is .NET, does all things subversion does generally, will integrate into full Visual Studio (but not Express, which is what I'm using at the moment) and is backended by SQL Server Full/Express.
So:
1. Who's using revision control?
2. What are you using?
3. How is it working for you?
4. Gotchas / tips
Cheers,
Glenn.
