Well I can only speak from a personal perspective but in the same way I don't expect my buyers to leave feedback I don't expect a thank you from a poster when I've been able to give them advice to help them sort out a problem. Yes it's nice when it happens but there really is no point in having that expectation.

Whilst some posters who start threads are a tad confused and think they are 'talking' to members of ebay staff, it is very easy to correct them on that and then go on to give them some advice.  I have found that some responders just tell them that we're not ebay, just ordinary members and leave it at that which is of no help whatsoever to the OP.
