Signed up with a spoof email address and profile to browse, but I am not convinced there are enough 'willing particiapants' on there that justify the signup fee of £50 a month (reduces to £35 if you pay for 6 months) to be able to send and reply to messages, find civvies desperately wanting to be fucked by afflunet horny men like me. Or indeed WGs touting, of which I've found seldom few.
You could sign up for 6 months, costing £210, and get bugger all out of it.
