Well, Carol, that is certainly a lot of questions.

Since I think Brian has gone to bed by this point, you got me--I am the developer.
First, it helps if you break this up into separate posts so others will be more likely to want to assist as well.
1. We set the font size for the menu links. Not going to change that at this time.
2. You got the member login dialog. That is not membership management. That is what your members use to log in so that they can get access to features and content only available to members. The drop down appears once you type the first 4 characters of someone's name in the name box of that dialog. You cannot access the Admin Console from the member login, only the admin login.
3. Well, you can put arbitrary events in the calendar just by double clicking any date. However, the catch is that arbitrary events are not meetings in the system. You only get events showing up in the Calendar as meetings if you create a meeting agenda for the date in question in the agenda system.
4. Because you did not set it up, probably. A club officer has to set that up in Club Central. See here:
support.toastmastersclubs.org/component/...s-international-site
5. I don't know... how long ago was your prior website active? If it was on FTH 1.0, all that stuff was deleted a long time ago when FTH 2.0 was released.
6. Give him the admin password so he can also access the admin console. We give you only one admin password... if you want to share with others that is up to you. There is no such thing as "admin access", just a single admin password.
Lastly, please familiarize yourself with our online documentation. A lot of your questions will get answered there, also.
