Merry Christmas Lee,
The users of the network appreciate your diligence on making the BCFMCA network as reliable and full featured as it is. Running Allstar has made it much more accessible. 
A big thanks to Doug and Dave for all their work to make this system available to us. 
Happy holidays 
Dave
