You probably landed here because page was mentioned on a forum. Indeed, I’m quite active member of 2 main forums (international and national) with more than 14 000 posts in total and Forum Guru / Admin status. I’m also not-so-active on few other forums/discussion groups/etc. See these main forums:

My nick: Kaper is the same here and there (and on some other, not necessarrily excel-related, forums too 🙂 ).

Enjoy the site!
