Group only or whitelist?

group its nice

Whitelist has the conveniency of not using up one of the maximum 1000 steam group slots.
But then you gotta add everyone to the list.
I'd say it's a more personal thing.

As a group you can track your stats on steamgifts(not sure if you can do that with whitelists).
And everyone who joins, if they wish, they can make giveaways for the group.
If the group isnt restricted, anyone can join.

I'd prefer whitelist as it would to go a much smaller userbase, having a bigger chance of winning.

There isn't a "best choice". I regularly mix and vary my setup for none-public GAs.

Both of option all use is not bad.

Prefer? group with whitelist?
Alls good with me on whatever you decide. Thanks for the past GA's

A better option is a whitelist. You will be sure, that the game will be won by people who you're selected yourself.

You know you can do both, whitelist AND steamgroups, right?

Thank you for your feedback, indeed there is not really a best. I will likely use both options.
