If a browser is not supported, display a message as such

Dear Team wpDiscuz:

I’m in an organization that, like a lot of others still, uses IE11.

I realize IE11 isn’t supported.

However, when the plugin loads, instead of leaving a blank area where the form should be giving the user the impression nothing is happening, it would be nice if you could display a message stating that the browser they’re currently using isn’t supported.

That shouldn’t be too difficult since a multitude of other plugins and websites do the exact same thing.

It also helps in the overall user experience. At least they know they need to change browsers instead of thinking that the website your plugin is on is broken.

Thank you.
