Verb conjugation of "bummeln" in German

I have been living in Holland for the last 14 years and I know the mentality very well. Holland is a small country, everybody knows everybody, so if we want to succeed, we must seize the opportunity.
Sometimes I visit Vocabulix to meet new people. It is true that one could do the same on Facebook, but the FB page is rather for friends, and you are less likely to contact strangers for this purpose.
I have not managed to contact you. And please write me only to the Vocabulix inbox and not directly to my other email addresses? When is the best time to reach you? For me anytime is good.
