Touchbase 2 uses 'Gaggle Mail' as the underlying technology for managing our mailing list, and sending out emails. We are using one of their basic, free accounts, which used to allow members of the group to send an email to a special email address provided by Gaggle, and it would automatically be sent through to all members of the group without everyone having to know the email addresses of all the members.
Unfortunately this facility is no longer available for free, and you will have to do things in a slightly more complicated fashion, and using your browser rather than your email program. It's a fairly simple process, and is illustrated step-by-step in a PDF file you can download - but basically, the procedure is to
visit https://gaggle.email.login, type in your email address (the one you told us about when setting up your TouchBase 2 membership), and then either click the 'sign in with email' link, or 'sign-in manually'.
If you chose the former option Gaggle will send you an email with a magic link in it, click the link, and you will be logged in! (The link works only for a limited time, and it is single-use. The 'manual' option will avoid the need for the verification email phase, but it does require you to have set a (free) account with Gaggle; if you are likely to be sending posts often, it is probably the best approach.)
Once logged in, click the green Touchbase button to confirm which group you are wanting to talk to, and on the next page there's a red 'compose' button that allows you to put together your post - or you can select a message and reply to the sender.
Please remember when posting messages that you should follow the guidelines, and in particular you should not send large pictures: we have a very small daily allowance, and once that's used up other people won't be able to make any posts. Visit the FAQs to see some hints on ways to reduce the space used by pictures before you send them!
