I play Bridge once per week. However we never know who will sho up. So I want to set up a web site where people can leave messages like " Mary-I will be there this Friday or Jim-I’ll be late.The messages should be dated. Anyone should be able to see the site.
You would need one of the many CMS options available. You would need to give each person login credentials, they would need to open a web browser, and log in, and make updates.
Then use one of the inexpensive CMS stacks like Kuler Edits or Sentry. Give everyone the same log in. Then they just go to the page, click the padlock, login, add their bit of text to the text window, save and exit. Don’t know how these stacks would cope with two people trying to do the same thing at the same time though.
Alternatively, use MicroBlog to embed a Tumblr blog in RW and people can email in their availability - Tumblr has a feature whereby you can email in blog entries and you as the admin get to approve them.
Don’t know why you’re trying to do this with RapidWeaver or any website. These type of “messages” Don’t appear to have any privacy concerns. (WhatsApp is Facebook, GroupMe is Microsoft) And even if if they did a website is probably not the best solution.
Or how about this: I have an add-on called contact form. This could gather the info. It normally sends it to me as an e-mail. Is there any way to capture the text and print it on a stylized text page?
You could try embedding a guestbook maybe? I don’t have any recommendations on a specific one as I don’t use them but I imagine you could find free ones.
