welcome to Rocrail!
of course Rocrail has bugs too ( take a look at Sourceforge) but mostly they can be solved quickly by our glorious coders
and Rocrail does not cost as much as Railware. It only costs some effort to read the wiki and write postings.
But don't forget: Rocrail is people! Any contribution is welcome, doesn't matter if you help others in the forum or write some wiki pages or code something ...
You also may feel free to donate the money you saved by not buying the next Railware update
