Hi, To get started with C# in general and MCS in specific, I was scribbling around with an implementation of System.TimeSpan. On the status page, I saw nobody was working on it (yet). I would be happy to finish my implementation and contribute it. When it's finished, I could take up some more substantial class(es) :-) Greetings, Duco Fijma (duco@lorentz.xs4all.nl)
