Got these from ASP.NET - yes, I am well aware that everyone who reads this will have seen these there...it's really just to remind me!
Anyway, great article on DotnetJunkies about Base Pages - these are just incredibly useful when trying to build a web site which has common functionality between pages without using some sort of template system like MasterPages.
The second is an article on WWWCoder on an email tracking system - which is really nice (and annoying, I just wrote this same functionality for a mail project I'm working on grr...).
Anyway, that's it for now...better get back to work before I get fired...
