Alan Johnson question

Hello,I dont know if anybody knows about Alan Johnson, He is a BBC reporter based in Gaza who was kidnapped from his office on the 12 of March. There has not been much news about him although it is said that he is alive.My dad worked in media and he was a familiar face around the BBC center. In a bid to secure his release, the BBC has made a link in the form of a button (which can be viewed here http://news.bbc.co.uk/1/hi/in_depth/world/...on/default.stm) They are urging people to put it in as many places as possible.Is it ok if i have it in my signiture? i can get rid of the pmdg one for time being if needed. Just dont want to break the rules!Thanks in advance,Dave
