Lvl 0 is fine, you give a chance to anyone :)

I will suggest start at lv1, which is almost no restriction.

Depends how you see it. From the way I see it, you can either go with an SG check for some basic things to avoid "leechers leechers" and rule breakers or you can go a similar way with levels since it's actually quite easy to get the first 3-4 at least, imo. From there it gets progressively harder to get levels so it's entirely up to you.

Up to you =)

how strict you handle your trains is up to you
i wouldn't though
too many leechers around

lvl 0 is ok, keep doing in like that please

it looks great as it is, thank you for chances

well, i only make giveaways that have level one if i believe the game is worth it - for example it's really popular and pricey.

On the one hand, level 1 means giving away one game.
On the other, if a level 0 wins a couple of games, and is able to sell any cards generated, they can buy a very cheap game to giveaway and become level 1.

There are positives to both aspects

I'd say level 1 so that there is less chance of winners not even knowing how the site works (and then you have to chase them down/explain how to activate codes/etc...).
Then again we all were poor level 0s at some point.

You decide!!! You are so generous with all! :)

I don't know...
We were all level 0 at soe point...
...but on the other hand it seems to me, that especially level 0 people did not read descriptions...
Maybe Level 1, since you can reach that with only one giveaway...
...but maybe it's enough to make invite only giveaways (trains) via the forum...
