If you're working with .NET / Visual Studio, you could look at adding them as code snippets
Code Keep is a pretty good online repo for CodeSnippets and has plugins for VS2008
What we've done at work is created a common account for the dev to use, so everyone submits to codekeep under a common login and then can retrieve everyone elses snippets.
Also it might be worth your while creating a developer wiki on your dev network. Somewhere that the old hands can leave documentation on your regularly used patterns & snippets and new team members can check for help. We use TRAC in house as an all in one WIKI / Issue Management / SVN Integration and it does the job nicely
