Design a landing page for Discord

[lauggh]

Currently, worldiaday.org/discord redirects immediately to https://discord.gg/dfBm4xv

But... as a best practice, we should have a landing page and include the following information about the WIAD Discord and set expectations.

• type of activity/engagement -- Maybe a list of channels and descriptions?
• code of conduct?
• direct Discord invite: https://discord.gg/dfBm4xv
• getting help/support with the WIAD Discord?

As well as the following:

• resources on how to get started with Discord?
• suggestions on how to get the most out of the WIAD Discord server
