SGT Le, great ideas, I was thinking along the same lines of perhaps an admin to send an invite, but even better if you are willing to approach SGT to Sgt... also, there's probably no real "sales" necessary as the network pretty much sells itself... although, you could probably include a published article on RallyPoint that would show that this is a reputable and valuable network. There's a variety of articles out there, attached below is among the relatively recent articles on RP and the future direction of the network. Thanks for your help, good luck, and if you need anything please don't hesitate. http://www.bizjournals.com/boston/blog/startups/2014/01/rallypoint-linkedin-for-the-military.html?page=all
Ok taking SGT Le advice I present myself in his tweeter and posted the rally point link on his other FB profile to invite Service members and veterans into RP. As per Maj. Burns advice.
It's just a waiting game now. :)
