This site is dedicated to helping I.T. professionals find out how their talents can be used in missions, or simply connecting them with other like-minded folks already in the mission field.
They hold multiple conferences throughout the year to accomplish this connection. And while it is still a conference, and who can really get excited about too many of these?....
the thing I enjoy about it is that they have IT professionals talking from experience and education about missions, TO I.T. professionals.
I remember going to conferences when searching out missions and asking "how can you use a unix admin with a network background?" and I'd get glazed stares.
It is nice to hear "oh, well, there are several places we have deployed servers and several people I could put you in contact with."
For that purpose, it's a decent conference, and I'll tote it.
