Hi, I'm a student of linguistics from Germany who is really interested in this project. I registered long before actually editing here. Before that, I made quite some edits in the German Wiktionary (my user page) but now I'm inactive there since it always seemed too prescriptive to me and so I found the English version a lot more interesting.
I'll try to help out here by editing mainly German entries (especially adding IPA transcriptions). Currently, I'm also going through Wiktionary:Requested entries (German), checking for citability and adding what I can :) I'm not the most regular editor, though.
