SIPO / PISO Shift Register libraries

Hi,

I am new here, and wondered what the process is for sharing two libraries that I have created for handling "unlimited" SIPO and PISO Shift Registers.

I would also like to get an opinion if the code can be optimized further.

Should I just add the libraries on my personal site, and then someone will link to it from the Arduino Playground? Let me know and I will share.

Thanks.
