The above two members have been selected as a "TFP Expert".
That designation is very meaningful in a variety of ways...
They have demonstrated expertise in the subjects which they discuss....their posts carry weight.
They convey that information in a concise and friendly tone to everyone. The importance of brevity and friendliness is just one of the reasons TFP is, by far, the premier pool forum on the internet.
Folks like smykowski and Isaac-1 generously share their time and knowledge here, so "hat's off" to them both.
