I'd love to help out by testing also.
My experience is
Playing computer games since 72 (Mainframe games as my father was in collage at the time) and the following beta projects over at PDS
HOI3 Their Finest Hour: Beta
EU4: Beta
V2 Heart of Darkness: Beta
East vs West: Alpha
I'm also one of the 4 guys that is the main team behind BlackICE, a mod for Hearts of Iron. I mainly do modifications to the lua.
My free time is kinda hit or miss though so, I may not always be available. If you are not limited to the number of testers you need, I do bring excellent testing abilities to the table.
end result though, once it's out I will be buying it
