Umseting - Enskt-Franskt - Because I was one of the first organizers...

According to what I found in an online English to French dictionary, I'd rather use the term "association" to translate "organization", first as it avoids an unhappy kind of stumbling way of speaking, and then because members have to pay smthg.
I found "association" here

And about "grandfathered", I think it is meant "seniority, length of service, notion of being upgraded from ground-member to care-member)
so in French we say "bénéficier de l'ancienneté", there isn't any shorter term for that (unless there is, but I don't know it)

"Grandfathered" is from grandfather clause (an exception).

pirulito is right, Francky - is the phrase you chose still correct?

No, I'll use "exemption" instead of "ancienneté", as "grandfathered" is unstranslatable into French, then also because consequences or the grandfather clause consist to exempt people who benefited from the former statute to be submitted to the new one and be injured by this new statute.

Non, je vais remplacer "ancienneté" par "exemption", étant donné que "grandfathered" est intraduisible en français, et puis aussi parceque les conséquences de la "grandfather clause" ont pour effet d'exempter les personnes ayant bénéficié de l'ancienne loi ou de l'ancien réglement d'être soumis à la nouvelle loi et d'être lésés par celle-ci.

I'll just add" loi d'" to "exemption, as this "grandfather" stuff is a legal one...

I had a further look on the internet at how could be translated "grandfather" clause, and it is translated in some Wiki file by : "La clause de non rétroactivité", so as it seems to be a little more accurate, as a translation, than the one I used, I'm going to edit with that...

Thanks so much for helping me with this, Francky & Pirulito (and so2000)!
