Point taken Les! Didn't mean to sound critical - just thinking out loud! (And wondering whether I've asked for too many lookups!)
I think when I first started I could hardly find anything for myself, even though I had subscriptions, so I've learnt a lot from people who've done lookups for me. Maybe the person putting all the requests on the site is just very inexperienced and enthusiastic?
As for checking other people's findings, well I suppose I do. If someone finds a person I couldn't find, then I'll look up their suggestion, because if it's my family I may be able to pick up other clues that would help. But when I first started my research I think I did take what other people said as 'gospel' because everyone seemed to know loads more than I did. I learnt from experience when I realised some things didn't 'add up' and I had to go back and do loads of deleting and checking.
