I was playing on the open SAS Proving Ground server recently (had some good time btw, thx), and I found out that you play Raven Shield too (either Coop or Random told me). I downloaded it and found that it had several patches released (1.6 is the latest I think). So I came here, on this website, to find info about a version that you use, so that I can play on your RVS open server, and I failed to do so. Maybe I just didn't know where to look.
Anyway, I think that showing that info somewhere on the title page might be a good thing to do.
