Well, this thread is called "Introduce Yourself", so yeah: Hi everyone!
I'm The.Modificator (though most people simply call me Modi) and I am around the Uru community since 2003. After the first Uru Live was cancelled, I joined the good old COBBS H'uru forum and was active there for a while. (Before the big server crash under the name "Idmo" and after that as "The.Modificator".) I did some work on the COBBS Wiki and wrote one or two plug-ins for the old PRPExplorer. Besides being interested in PRP and especially Python hacking I also contributed some code to the Alcugs server.
During the UU times, I continued developing my own KI version which a friend and I used to create a storyline on a German-speaking shard that I also had admin rights for. (Actually the story was carried on to other English-speaking shards as well, but I didn't use my custom KI there.) I didn't publish any of that KI code though. (The reason for this was mainly that the only place where such code would be in more or less good hands was the Guild of Admins... and I was never invited there.

)
With the death of UU and the birth of the GameTap incarnation of Uru I pretty much paused all my work on hacking Uru. Since the workload of the real life increased during the GameTap time, the death of this Uru incarnation actually wasn't all too inconvenient for me. I disappeared from the community almost entirely. (With the exception of translating the Myst Online web pages to German and proof-reading some German texts for the Myst iPhone version.)
When I heard recently that Uru has come back yet another time, I joined the community once again. Since a lot of stuff changed since COBBS and UU times, I had to get used to Hacking Uru once again. But now I'm all set, ready for Open Source.

In the last few days I made myself familiar with the PRP structure once again (but with much more detail this time - thanks to all the work that was done in the meantime) and set up a contrib folder for me in the PyPRP SVN where I already committed some bugfixes and some Plasma GUI classes.
About my qualifications: I'm not all too bad at programming (in the relevant languages C++, Python, Java), I understand how Plasma deals with PRP objects (at least from an age designer's perspective) and I can do modelling in Blender.
I hope this is enough for an introduction.

Cheers,
The.Modificator
