New account

I have my personal library on Library Thing. Now I want to set up a small collection on Tiny Cat or Library Thing for the holdings of the local astronomy society. Do I set this up through my own account or do I create a totally new account, I'm guessing on TinCat? When I tried to set this u on TinyCat it asked me if I was a member on Library Thing and I said yes, but that did not feel right.

TinyCat is an add on to an LT account. You should create an organisation account for the society on LT. Note that while TinyCat is free for personal use, organisations need a paid subscription after the first month.
