How are we watching ep. 6?

[SweetTea]

I've just finished re-watching eps 1 & 2 and am on to #3. In about half an hour, the bottle of wine will be opened and I'll slowly start working on that.

Thankfully my hubby has agreed to keep our kids out of my way for the day while I re-watch everything. I've already warned him that when I'm watching the final ep, he will hear me cursing at my computer and that I will be crying a lot. I think he's figured out that it's easier to just let me do this than to say anything.

Can anyone tell me how long the episodes will be available on iPlayer? I'm watching from the States, so I'd like to know how long I have to watch before they are gone and I'm stuck waiting for the DVDs.
