I just signed up to wpmudev today... and I am wondering...
Do you have a plugin for split testing a website? How about a plugin for tracking marketing? Similar to these: http://www.splittestwordpressplugin.com/ and http://adtrackzgold.com/ The first one is a plugin, the 2nd one isn't, but I'm wondering if there's anything available here. If not, can you create them?
