Hi all,

 

I am sorry, I have not been on the forum so much over the last 3 days.  But I have been on for many hours tonight and have looked at  every post and given all the answerers the credit to which they are entitled.

 

Our wonderful answerers have been Rosala, NinjaDevo, Alan, draagonSlayer554, Heureka, Chilledz3non, Bugzy28871, CPhill, gliu1, AngelicaMarrufo, Coolkille98, Cooltjej98, Trwbox, Reaper, Landry, Red Ranger, Aoanewbie, Red11Blue22 and last but definitely not least Kitty<3.   Thank you.  You are all wonderful.

 

I would like to extend a very special thank you to CPhill.  Chris, you hold this place together when I am absent, you are at my side when I am here and your descency and fantastic sense of humour gives this forum its life blood.  Thank you so much Chris.  I really appreciate everything that you do.

This one has been around for ever - that is because it is so good!

I have hidden CPhill's answer so if you want the answer from a moderator you might have to beg.   LOL
