It must have expired....I haven't had time to even think about building sliders lately. My wife is a full time nursing student in a 10 month accelerated RN program. I work, take care of our son, and keep the house/place up so that leaves me with about enough time to sleep. However, in December she has a couple weeks off from school. I plan on building a couple sets of sliders during that time. I don't think I want to take any orders in case I can't get them finished within a reasonable amount of time. Once they are built I will let you guys that have PM'd me know.
