Using this blog function of your new site for a “news feed” can greatly simplify handling the dated content of your site.
It means that the person putting up dated information (“Pancake Fundraiser this weekend!”) ONLY has to focus on PUTTING UP new info, and is relieved of having to take dated info down!
You can leave dated info on your site past the date — only if you leave it in a blog, and you have newer, more recent posts– and people can see what your church has been doing in the recent past.
AND, you can more easily link to dated info in your other media– not only email and social media, but also print media.
In using this strategy, your website news feed becomes the “hub” where people find the full information on dated news and events.
