If you have a friend with netflix you could just ask for their login...that's how most people I know watch stuff.
Netflix is how I watch it I also have all ( I think all seasons) on a hard drive. But I'm not sure how many season there are is it 4 or 6?
If the Netflix bit doesn't work out, you can try searching up individual episodes on Google Video, and if that doesn't work, search on regular google for '"The L Word" episodes online'. That's what I do.
Sidereel.com is a good place to look for free episodes if you can't get them on Hulu, Netflix, or the network's website. I have no idea about that show specifically.
