Hi Zoomy,
There are two main match systems covering matches scheduled in Germany, although it's worth noting that they typically also include matches in a number of other European countries (these tend to be primarily The Netherlands and Austria). Neither one of these systems is particularly friendly in terms of user interface, but once you've used them a couple of times, they become somewhat more intuitive. You can find them here:
Match Organisation System (MOS) - This is the main system for match scheduling and registration
http://www.ipsc-dvc.org/index.php?option=com_ipsc&Itemid=35&task=Wettkampf_Liste
Secondary match registration system (the ones that appear here will not appear in the MOS system above)
http://ipscmatch.de/index.pl?lang=en
You'll need to register for both sites before you can access any of the materials associated with the matches (i.e. detailed match descriptions, invitations, etc.), but this shouldn't be a problem. Both sites are available in English.
Not sure what your dates/availability might be, but there are two upcoming Level 3 matches I've signed up for:
1) STI European Challenge, August 15-17 (match has its own website here: http://www.sti-euro-challenge.eu) - Takes place in Hodonice, Czech Republic, but if you're in Bavaria this will not be far from you
2) MOS Autumn Edition, October 3-5 - Takes place in Lauf an der Pegnitz, just East of Nürnberg
If you prefer not to register for either of the sites right away, but just want info on a specific match, just let me know and I can send you the descriptions as a PDF by email. My address is: IPSCtraveler@gmail.com
