WAEC 2010 Recruitment hopefuls...read this and comment

Hello house
I have received request from WAEC on 3 occasions asking for same type of additional docs since they conducted their test in late last year 2010.

Two times (Feb and March) I received the request from an addy with sidmach.com and the latest 1 last week from same addy but to be sent to an addy with yahoo.com

Has any1 be getting this? Any1 in the house who is familiar with WAEC recruitment procedure; is this their usual way? Kindly respond and/or post a constructive overview on this matter.
Thanks.
