'is it a real community or is it staff in India or Singapore '
most are uk customers who use their knowledge to help other customers.
for example my real life experience is in dealing with complaints/the ombudsman/anti scamming/certain technical things. someone like ravenstar is a whizz with anything email related. others are good all rounders. everyone though does it for nothing and in their own time.
i'm quite prolific on a large ppi forum, the sky forum and IT and anti scamming forums. again they are community based using customers/those in the know. we do have a few indians in the anti scamming areas i go to. and jolly nice people they are too.
