You may win a free ad spot on my right sidebar. All you have to do is to make a tweet containing my blog url "http://www.kreci.net" (without using shortening url services). I will search and choose one random (or most creative) tweet every month and give you free banner spot for 1 month! You may put any graphic or text ad up to 125x125px (without offensive or adult content).
Additionally this ad will be "Do Follow" for search engine! My site is very well indexed in google so I am sure you will benefit from it. You may click Tweet & WIN link on my right sidebar to make a tweet (use my default or make any other - be creative - just make sure that it will contain my blog URL). Good Luck!
