Good online classes to learn sign language?

Currently I am learning sign language from a coworker (along with a few other coworkers) as a trainer at my job to be able to train our deaf employees better. I am looking for any online classes, websites, anything really that will help me along with it. Any suggestions are welcome, I already use www.aslpro.com 🙂 Thanks in advance!!!
Hehe thanks Sania, my fingerspell is pretty darn good now tho. I was looking more for common every day sentences, how to string words together, stuff like that. Everything I am learning at work is work related (manager, supervisor, meeting, etc….) so I want to learn the common words so I can converse in sign. Thanks tho 🙂
