I spend a lot of time contributing to m0n0wall, pfSense, and other miscellaneous open source projects, and network and security related mailing lists. 

Amazon wishlist
I read an average of an entire book a week to further increase my knowledge in these areas. 

Help me help you, and motivate me to continue this work.  Buy me something from my Amazon wishlist.

You can send a PayPal contribution to <paypal at chrisbuechler dot com>.  I use this money to pick up various pieces of equipment for testing purposes.
