Does most of your DnD internet communication happen here, or on Facebook, Discord etc?

I dont have facebook account, rarely launch discord and dont speak to anyone personally who collects anything I collect.

I am just asking. I am not lonely, but I guess it is a lonely question.

Facebook has a few groups that you might want to consider joining.  You don't have to create an elaborate account to join Facebook either.

Just be aware that you might have a higher chance of encountering trolls on Facebook, but if you stick to specific groups, most extraneous controversy can be avoided.

In no order of preference:

https://www.facebook.com/groups/rpgcbg

https://www.facebook.com/groups/531948453671423

I'm sure there are some that I've missed.

There are also groups that are devoted to auctions, sales, and trades.  Here are a couple:

If you are looking for groups that are more general D&D or convention specific:

This is in no way a comprehensive list.  Perhaps others will share their recommendations.

You can create an account that no one will be able track you down with.
