If we are going to have a place for say pensioners from a particular department. What kind of approach will you take to keep in touch and interact with each other ? Is there any scope of building a website for this ?
I think a WhatsApp group will be fine as long as the old age folks know how to do it. But mostly we will have to give them a better screen to interact. What method will you use to build such a website ?
Big screen options are better. Provided your targeted audience know how to use computers. Either WordPress or PHP. I don't see the need for more complicated options.
