Nuno: I do use synapse in my projects that need network code (it even has serial support) which is really useful. If I recall, theres tutorials and documentation that is quite thorough in the source archive which I found sufficient to get going as I mentioned earlier. As for use in games - I have toyed with making a simple 2D MMORPG type engine and synapse worked wonders. Seeing as I did it just to see how hard it would be I got to the point where everything boots (server and client) and assets can be fetched/received from the server and data can be synced back and forth but beyond that it was pretty much just a question of content. What I can say is thats its a robust library that makes things very easy to code (said code was about a day and half of on/off lax development).

If anyone has any queries, I'll gladly help out if its something I ran into though nothing really comes to mind off the bat
