In the past, although not recently, I have done work through them.
I just keep looking. Some companies call or email with offers. When I have a request, I put it in my calendar on the day I said I could do it with a big R in front of it. If it is given to me, I mark out the R. I have a couple of requests right now that went past the "assignment" date. The company said they were still working on them. I haven't even looked at their website recently. Except for entertaining myself here, I am very busy with work.
